Go math I need help with number 13 on page 421


The recipe calls for 2 2/4 cups, but julie only has 1/4 cups. We need to divide the number of cups needed for the recipe by 1/4. The first step we need to take is to convert the mixed fraction to an improper one. This is done below:
[tex]2\frac{2}{4}=2+\frac{2}{4}=\frac{8}{4}+\frac{2}{4}=\frac{10}{4}[/tex]Now we can divide them:
[tex]\frac{\frac{10}{4}}{\frac{1}{4}}=\frac{10}{4}\cdot\frac{4}{1}=10[/tex]She will need to use 10 of her measuring cups.
