Ber [7]

7 out of 50 is the same as 7/50

First, change the fraction into a decimal by dividing.

7 / 50 = 0.14

Second, change the decimal into a percentage by multiplying by 100%.

0.14 * 100% = 14%

18 out of 20 is the same as 18/20

First, change the fraction into a decimal by dividing.

18 / 20 = 0.9

Second, change the decimal into a percentage by multiplying by 100%.

0.9 * 100% = 90%

Best of Luck!
