Question

If Julia needs 3 1/4 cups of oatmeal, how many 1/4 cups of oatmeal will she use

Answer 1

Julia needs 3 $\frac{1}{4}$ cups of oatmeal, and she can only get it in $\frac{1}{4}$ cup quantities at a time. We know that $\frac{4}{4}$ makes 1 whole, so we need to multiply the amount of whole cups she has by 4.

3 * 4 = 12

Finally, we see that there is $\frac{1}{4}$ cup of extra oatmeal that Julia wants, so we add one more to our sum.

It will take 13 sets of $\frac{1}{4}$ cups of oatmeal to make 3 $\frac{1}{4}$ cups of oatmeal.
Hope that helped =)
