Question

A vendor sold 72 hotdogs and hamburgers during a football game if the ratio of hotdogs to hamburgers sold was 8:1 how many of each food did vendor sell?

Answer 1

$\bf \cfrac{hotdogs}{hamburgers}\qquad 8:1\qquad \cfrac{8}{1}\qquad \cfrac{8\cdot \frac{72}{8+1}}{1\cdot \frac{72}{8+1}}\implies \cfrac{8\cdot 8}{1\cdot 8}\implies \cfrac{64}{8}$
