$\rm \hookrightarrow \: 5 \: dozen \: cookies = 12×5 = 60 Cookies$

60 cookies need 4 cup of flour

$\rm\hookrightarrow1 \: cookie \: need (4)/(60) cup \: of \: four$

$\rm \hookrightarrow90 \: cookies \: need (4)/(60) * 90 \: cu p \: of \: flour$

$\rm \hookrightarrow = (4)/(2) * 3$

$\rm \hookrightarrow = 2 * 3 = 6 \: cups \: of \: flour$
