Step-by-step explanation

1. Convert percentages into fractions or decimals

For fraction: divide 42 by 100 and remove the % sign.
$42 % = \frac{42}{100}$

For decimal: move the decimal point 2 places to the left and remove the % sign.
$42 % = 0.42$

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

$100 % = 70$
$\frac{42}{100} \cdot 70 = 0.42 \cdot 70 = 29.4$

42% of 70 is 29.4
