Question

3\4 gallons of stawberies in 1\2 hour how much in 2 hours

Answer 1

$\bf \begin{array}{ccll} \stackrel{strawberries}{gallons}&hours\\ \cline{1-2}\\ \frac{3}{4}&\frac{1}{2}\\\\ x&2 \end{array}\implies \cfrac{~~\frac{3}{4}~~}{x}=\cfrac{~~\frac{1}{2}~~}{2}\implies \cfrac{~~\frac{3}{4}~~}{\frac{x}{1}}=\cfrac{~~\frac{1}{2}~~}{\frac{2}{1}} \\\\\\ \cfrac{3}{4x}=\cfrac{1}{4}\implies 12=4x\implies \cfrac{12}{4}=x\implies 3=x$
