Question

if you can feed 36 dogs with a 24 pound bag of food, how many dogs can you feed with a 16 pound bag of food?

Answer 1

you can feed 24 dogs with a 16 pund bag

Answer 2

`\bf \begin{array}{ccll} dogs&lbs\\ \cline{1-2} 36&24\\ d&16 \end{array}\implies \cfrac{36}{d}=\cfrac{24}{16}\implies \cfrac{36}{d}=\cfrac{3}{2}\implies \cfrac{36\cdot 2}{3}=d\implies 24=d`
