Question

How do you convert 9/45 into a percent and decimal?

Answer 1

Divide the numerator by the denominator to change the fraction into a decimal fraction. Then multiply by 100% to change it to percentage.

Explanation:

A decimal fraction is a fraction with the denominator as fractions of `1/10, 1/100, 1/1000 1/10000`

`9/45 = 1/5 = 0.2 or 2/10 or 20/100`

A percent is a fraction of 100 as a given denominator, so multiply the decimal by 100% moving the decimal point two places to the right.

`0.2 xx 100%` = 20% see above `20/100 = 20%`
