Changing percentages to fractions

The word percentage means out of 100. We use the % sign to show percentage.

10 squares out of 100 are shaded. This could be written as 10%.
Writing this as a fraction you could say that 10 squares out of 100 are shaded.
10% = $The fraction 10 over 100.$ which can be simplified to $The fraction 1 over 10.$ .

To write a percentage as a fraction put the number over 100 and simplify if possible.

Here are some examples of writing percentages as fractions:
          5% = $The fraction 5 over 100.$ = $The fraction 1 over 20.$
        25% = $The fraction 25 over 100.$ = $The fraction 1 over 4.$
        50% = $The fraction 50 over 100.$ = $The fraction 1 over 2.$
        75% = $The fraction 75 over 100.$ = $The fraction 3 over 4.$
        40% = $The fraction 40 over 100.$ = $The fraction 2 over 5.$
        20% = $The fraction 20 over 100.$ = $The fraction 1 over 5.$
