Question

Should I divide or multiply for this math problem: Nick spent 1 3/4 hours doing homework. Of that time, 2/3 was spent on a social studies project. How many hours did Nick spend working on the project?

Answer 1

Multiply.

$1 \frac{3}{4} \times \frac{2}{3}= \frac{7}{4} \times \frac{2}{3}=\frac{7}{2} \times \frac{1}{3}=\frac{7}{6}=1 \frac{1}{6}$

Nick spent 1 1/6 hours working on the project.
