Fractions, decimals and percents

Fractions, decimals and percents

1. To change a fraction to a decimal you must divide the numerator by the denominator

   • Example: 5/8
     • Then, you have to multiply the decimal by 100 to change it to a percent
       • (.625)(100)= 62.5%
   • Now you have a decimal!!! To change the decimal to a percent you must multiply the decimal by 100

2. To change a percent to a decimal, you must divide the decimal by 100

   • Now you have a decimal! If you want to change your percent to a fraction, you can set your percent over 100 and then simplify the fraction by finding the greatest common factor between the numerator and denominator.
     • Example: 50% = 50/100 = 1/2
   • Example: 50% = .50
