How to convert a fraction to percent?
Divide the top of the fraction by the bottom, multiply by 100 & add % sign.
Ex. 2/3 = 66.7%
change the fraction to a percent 5/9
Change the fraction into a division problem and solve
.Move the decimal behind the hundredths place in the quotient.
.Drop the percent sign after the new number.
How to convert a percent to fraction?
Step 1: Write down the percent divided by 100 like this: percent/100
Step 2: If the percent is not a whole number, then multiply both top and
bottom by 10 for every number after the decimal point. (For example, if
there is one number after the decimal, then use 10, if there are two then use
100, etc.)
Step 3: Simplify (or reduce) the fraction
Ex. 75% = 75/100 = 15/20 = 3/4
Convert 62.5% to a fraction
