express each percent as a common fraction or mixed number. 17. 30% 21. 12.5%

Answer

Explanation:

Step1: Convert percent to fraction

Percent means per - hundred. So $12.5%=\frac{12.5}{100}$.

Step2: Remove the decimal

Multiply both numerator and denominator by 10 to get rid of the decimal in the numerator. $\frac{12.5\times10}{100\times10}=\frac{125}{1000}$.

Step3: Simplify the fraction

Find the greatest - common divisor (GCD) of 125 and 1000, which is 125. Divide both numerator and denominator by 125: $\frac{125\div125}{1000\div125}=\frac{1}{8}$.

Answer:

$\frac{1}{8}$
