• Fraction
A fraction is a number between zero and 1 and is expressed as one number over another number, like this:
The number on top is called the numerator and the number on the bottom is called the denominator. It means that if you cut up a whole into 2 parts (the denominator), then the fraction is 1 of those 2 parts, or a half. When you think of a fraction, think of a pizza!. Suppose a pizza is cut evenly into 8 pieces. These 8 pieces are the denominator. Now, if you ate 3 of them you ate 3/8 of the pizza. This is not quite half of the pizza. Half of the pizza would be how many pieces? That's right, it would be 4 pieces. This makes the fraction 4/8 which can be reduced to 1/2 or 'half' of the pizza. A fraction can be converted into a decimal or a percent. The following table shows you how to convert between fractions, decimals and percents:
... to a fraction... to a decimal... to a percent
From a fraction ... Divide the numerator of the fraction by the denominator
Example 3/4: divide 3 by 4 to get .75
Convert to a decimal, then multiply by 100
Example: 3/4 is the decimal .75
.75 X 100 = 75%
From a decimal ... If the decimal has 1 number past the decimal ===> Multiply by 10 to get the numerator and make the denominator 10 Example: .7 X 10 = 7Fraction is 7/10 If the decimal has 2 numbers past the decimal ===> Multiply by 100 to get the numerator and make the denominator 100 Example: .72 X 100 = 72Fraction is 72/100 If the decimal has 3 numbers past the decimal ===> Multiply by 1000 to get the numerator and make the denominator 1000 Example: .725 X 1000 = 725Fraction is 725/1000
Multiply the decimal by 100
Example: .38 X 100 = 38%
From a percent ...Make a fraction by making the percent the numerator
with a denominator of 100
Example: 38% = 38/100
Divide the percent by 100
Example: 38%: divide 38 by 100 to get .38
