1. Convert percentages into fractions or decimals

For fraction: divide -20 by 100 and remove the % sign.
$- 20 % = \frac{- 20}{100}$

For decimal: move the decimal point 2 places to the left and remove the % sign.
$- 20 % = - 0, 2$

2. Multiply the decimal or fraction by the quantity that equals 100%

$100 % = 72$
$- \frac{20}{100} \cdot 72 = - 0, 2 \cdot 72 = - 14, 4$

-20% of 72 is -14,4
