Answer

36 hours is 120% of 30 hours.

Work Step by Step

$\frac{part}{whole}=\frac{percent}{100}$ $\frac{36}{x}=\frac{120}{100}\longrightarrow$ Cross multiply then solve for x $120x=(36)(100)\longrightarrow$ Simplify $120x=3600\longrightarrow$ Divide both sides by 120 $120x\div120=3600\div120\longrightarrow$ Simplify $x=30$
