Question

Write a proportion that could be used to solve for each variable. Then solve 60 pens in 25 boxes


12 pens in y boxes

Answer 1

pens over boxes equals pens over boxes
\[\frac{60}{25}=\frac{12}{y}\] or
boxes over pens equal boxes over pens
\[\frac{25}{60}=\frac{y}{12}\] or
boxes over boxes equals pens over pens
\[\frac{y}{25}=\frac{12}{60}\]

Answer 2

doesn't matter what ratio you use, you get the same answer
\[y=\frac{25\times 12}{60}\]
