Question

Jon needs to buy 4 1/8 feet of packaging tape. There are 1 3/8 feet of tape on each roll. How many rolls of tape should Jon buy?

Answer 1

we have to divide the mix fractions, bet first let us change it to normal fractions

$\begin{gathered} 4\frac{1}{8}=\frac{32+1}{8}=\frac{33}{8} \\ 1\frac{3}{8}=\frac{11}{8} \end{gathered}$

now we can divide them

$\frac{\frac{33}{8}}{\frac{11}{8}}=\frac{33}{8}\cdot\frac{8}{11}=\frac{33}{11}=3$

so he should buy 3 rolls
