Question

One serving of Chad's favorite cereal contains 1 1/4 ounces. How many servings are in a 15 1/3 ounce box

Answer 1

so namely how many times does 1¼ go into 15⅓?

let's firstly convert the mixed fractions to improper fractions and then divide.

`\bf \stackrel{mixed}{1(1)/(4)}\implies \cfrac{1\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{5}{4}}~\hfill \stackrel{mixed}{15(1)/(3)}\implies \cfrac{15\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{46}{3}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{46}{3}/\cfrac{5}{4}\implies \cfrac{46}{3}\cdot \cfrac{4}{5}\implies \cfrac{184}{15}\implies 12(4)/(15)`
