What is a simple fraction? - A fraction that is not top heavy like 2/3. What is an improper fraction? - A fraction that is top heavy like 3/2. Where is the numerator in a fraction? - The numerator is the top part of the fraction. Thus in ½ : 1 is the numerator while 2 is the denominator. Where is the denominator in a fraction? - The denominator is the bottom part of the fraction. Thus in ½ : 1 is the numerator while 2 is the denominator. Define the symbol =, <, > - = is equal to < is less than > is greater than What kind of numbers is 2¼, 2½, 3¾? - These numbers are examples of mixed numbers. What is an improper fraction? - It is a fraction where the numerator is greater than the denominator like 23/4. What are the steps of changing a mixed fraction to an improper fraction? Using example 2¾ - Using example 2¾. 1) Multiply 4 x 2 = 8 2) Add the sum of 8 to numerator thus 8+3= 11 3) Keep the same denominator and the answer is 11/4. What are the steps of changing an improper fraction to a mixed fraction? Using example 11/4 - Using example 11/4 1) Divide the mixed fraction. 11/4 is 2 with a remainder of of 3. 2) Thus it is 2¾. *please note that we kept the same denominator when applying the remainder. How do you change a fraction so you can add like terms? Use example ½ + ¾ = ? - Use example ½ + ¾ = ? 1) Determine which fraction you would like to change. In this case it would be ½. To add fractions, the denominator must be the same. 2) To change ½ we multiply both numerator and denominator by 2/2 to equal 2/4. *2/4 and ½ are the same fraction. 3) Thus 2/4 + 3/4 = 5/4 (an improper fraction) Whenever possible, when taking a test, reduce the fractions into ----- ----- ? - Whenever possible, when taking a test, reduce the fractions into LOWER TERMS What are the steps in reducing a fraction to its lowest term? Use example 8/16. - Use example 8/16. 1) Divide both the numerator and the denominator with the number that you determined will go evenly for both terms. In this case it would be 8 so 8/16 ÷ 8/8= 1/8 What are the steps in adding fractions with the same denominator? Use example 2/5 + 1/5 =? - Use example 2/5 + 1/5 =? 1) Just add the numerators because both fractions are like terms with the same denominator. Thus 2/5 + 1/5 = 3/5 or 2+1= 3 then place the denominator back 3/5. What are the steps in adding fractions with the different denominators? Use example 2/4 + 1/12 =? - Use example 2/4 + 1/12 =? 1) Find a common denominator by reducing a fraction or multiplying a fraction to make it into like terms. Thus 2/4 x 3/3 = 6/12 2) Add the like terms keeping the denominator the same. Thus 6/12 + 1/12 = 7/12 What are the steps in subtracting fractions with the same denominator? Use example 7/8 - 3/8 = ? - Use example 7/8 - 3/8 = ? 1) Just subtract the numerators because both fractions are like terms with the same denominator. Thus 7/8 - 3/8 = 4/8 *don't forget to reduce the fraction 4/8 ÷ 2/2 = 1/4 What are the steps in subtracting fractions with the unlike denominators? Use example 5/6 - 3/5 = ? - Use example 5/6 - 3/5 = ? 1) Find a common denominator by reducing a fraction or multiplying a fraction to make it into like terms. Thus the GCF (greatest common factor) of the denominator 6 & 5 is 30. 5/6 x 5/5 = 25/30, 3/5 x 6/6= 18/30. Using the new terms 25/30 - 18/30 = 7/30 Can mixed fraction be added or subtracted? - YES. Provided they follow the same like term rules with the denominator being the same. Can mixed numbers be added or subtracted? - YES. Provided they follow the same like term rules with the denominator being the same. Make your life easier by changing the mixed number into a mixed fraction and then add or subtract to eliminate common mistakes as long as they have like denominators. What is the general rule when multiplying fractions? - To multiply fractions. multiply the numerator to get the new numerator, and multiply the denominator to get the new denominator. What is the "shortcut" called cross cancellation when multiplying fractions? - Cross cancellation is where you simply the fractions diagonally from one another. Example *reduced 2 1 X 8* 1 2 __ __ = _ x _ = 2/15 4* X 15 1 15 1 What is the general rule for reading a decimal? - Numbers to the right of the decimal point have a value less than 1 and the numbers to the left of the decimal point have a value greater than 1. Review the decimals position as whole numbers into decimal numbers. - Ten thousands 10,000 Thousands 1,000 Hundreds 100 Tens 10 Ones 1 Decimal Point . Tenths .1 Hundredths .01 Thousandths .001 Ten thousandths .0001 What is the general rule for adding and subtracting decimals? - Place the decimals in a vertical column so the decimals all align and add/subtract. 102.60 3.02 +00.45 ----------- 106.07 What is the general rule for multiplying decimals? - The same method for multiplying whole numbers applies to decimals but the location of the decimal in the total depends on the number of places of the original problem. Example 6.3 X 7.6 ------ 378 4410 --------- 4788 ----> 47.88 (original problem has 2 decimal places) Why is multiplying by 10, 100 or 100- fast and easy to calculate? - Multiplying by 10, 100 or 100 is fast and easy to calculate by simply moving the decimal point the same number of places to the right, as there are zeroes in the multiplier. Example 0.712 X 10 = 7.12 (moving one decimal place to the right) 0.09 X 1000= 90 (moving three decimal places to the right) How do you divide a decimal by a whole number? - Divide a decimal by a whole number, place the decimal point in the quotient directly above the decimal point of the dividend. Example: 30.5 ÷ 5 = 6.1 6.1 5 ⌈------ 30.5 30. ----- 5 5 -- 0 What are the steps to divide two decimals? - Change the decimal number in the divisor to a whole number and move the dividend by the same number of places that you moved the decimal point in the divisor and solve. 1.2 ÷ 0.48 ------> 12. ÷ 04.8 = 0.4 Why is dividing by 10, 100 or 100- fast and easy to calculate? - Dividiing by 10, 100 or 100 is fast and easy to calculate by simply moving the decimal point the same number of places to the left, as there are zeroes in the multiplier. Example 0.712 ÷ 10 = 0.0712 (moving one decimal place to the left) 9 ÷ 1000= 0.009 (moving three decimal places to the left) How do you change fractions into decimals? - Divide the numerator by the denominator and place a decimal point after the dividend.Add zeroes as needed and make sure that the decimal point is directly above the decimal point the dividend and then divide. Example 3/8 0.375 8 ⌈---------- 3.000 2.4 ----- .60 .56 -- .040 .040 ______ 0 How do you change decimals into common fractions? - The decimal expressed becomes the numerator of the fraction. The number of decimal places to the right of the decimal will tell you what the denominator is. To change 0.75 = 75 ÷ ? 1 place = a denominator of 10 2 place = a denominator of 100 3 place = a denominator of 1000 Therefore 0.75 is expressed as 75/100 How do you change a percent (%) into a fraction? - 1) Drop the % symbol 20% to 20 2) Divide the number by 100 20 ÷ 100 = 1/5 3) Reduce the fraction to its lowest terms. 4) Change the mixed number is necessary. How do you change a fraction into percent (%)? - 1) Multiply the fraction by 100. 1/2 X 100/1 = 100/2 2) Reduce if necessary. 100/2 = 50/1 = 50 3) Change the improper fraction to a mixed number. 4) Add the % symbol. How do you change a percent (%) into a decimal? - 1) Drop the % symbol. When you drop the % symbol from a whole number, a decimal point takes the place of the symbol. For example, when you drop the % symbol from 68.1%, the decimal point replaces the % symbol. 2) Divide by 100 by moving the decimal point two places to the left. 68.1 = 0.681 3) Add zeroes as needed. How do you change a decimal to a percent (%) ? - 1) Multiply by 100 by moving the decimal point two places to he right. For 3.19 you would move the decimal point two places to the right, so 3.190 = 319.0 2) Add zeroes as needed. 3) Add the % symbo. 319.0 = 319% What is a ratio? - A ratio is used to express a relationship between two units or quantities by division. A slash (/) or colon (:) is used to indicate division, and both are read as "is to" or "per". For the ratio of "1 is to 2" you can write 1:2 or 1/2. The numerator is always to the left of the colon or slash and the denominator is always to the right of the colon or slash. What is a proportion? - A proportion states that two rations are equal. A proportion can be written as a common fraction from in which the numerator and denominator of one fraction have the same relationship as the numerator and denominator of another fraction. The equal symbol (=) is read as "as." For example: 1/3 = 2/6 1 is to 3 as 2 is to 6 How do you verify that two ratios in a proportion are equal? - For a fraction, multiply the numerator of each ration by its opposite denominator. The sum of the product will be equal. Example : 1/3 : 2/6 2 x 3 = 1 x 6 (by cross multiplying) 6 = 6 How do you solve for x? - 1) Write down what is available or known in a fraction format. 2) Complete the proportion by writing down what you desire in a fraction format, making sure that the numerators and the denominators are like units. 3) Cross multiply the numerator of each ratio by its opposite denominator. 4) Solve for X using division. Using the example solve for X. 75 milligrams of Demerol, a painkiller, is prescribed for a patient following surgery. The medication is available as a liquid solution, with each milliliter of solution containing 100 milligrams of Demerol. To administer the prescribed dose of 75 milligram _____ milliliters would be given? - 1) 100mg/ 1ml is known 2) The complete proportion by adding the known and what is desired using X. 100mg/ 1ml = 75mg/ Xml 3) Cross multiply 100X = 75 4) Solve for X. x= 3/4ml When letters or numbers are written together without any sign or symbol between them, you should assume that....... - When letters or numbers are written together without any sign or symbol between them, you should assume that...... multiplication should be used between those digits.
