Question

A recipe calls for 2/2/4 cups of rainsins but Julie only has a 1/4 cups how many 1/4 cups does Juile need to measure out 2/2/4 cups of rainsins

Answer 1

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

namely how many times does 1/4 go into 2 and 2/4.

`\bf \stackrel{mixed}{2(2)/(4)}\implies \cfrac{2\cdot 4+2}{4}\implies \stackrel{improper}{\cfrac{10}{4}}\implies \cfrac{5}{2} \\\\\\ \cfrac{5}{2}/ \cfrac{1}{4}\implies \cfrac{5}{2}\cdot \cfrac{4}{1}\implies \cfrac{5}{1}\cdot \cfrac{4}{2}\implies 5\cdot 2\implies 10`
