Question

Daniel picked 1 3/4 cups of blueberries, and Eva picked 2 3/4 cups of blueberries. They combined their blueberries, then used 1/3 of the blueberries to make muffins. How many cups of blueberries did they use for the muffins?

Answer 1

$amount \: of \: blueberry \\ \frac{7}{4} \ + \frac{11}{4} \\ = \frac{18}{4 } cups \\ number \: of \: blueberries \: used \\ = \frac{18}{4} \times \frac{1}{3} \\ = \frac{18}{12} \\ = \frac{3}{2} cups$
