Question

Out of $\frac{15}{4}$ hours, Charles spent $\frac{5}{4}$ playing and he studied for the remaining hours. How much time did Charles spend studying?

• A. $\frac{9}{4}$h
• B. $\frac{20}{4}$h
• C. $\frac{10}{4}$h

Answer 1

The correct option is C $\frac{10}{4}$h

Total duration $=\frac{15}{4}$h

Number of hours Charles spent playing $=\frac{5}{4}$h

Number of hours Charles spent studying = total number of hours - number of hours spent playing

$=\frac{15}{4}-\frac{5}{4}$

First, we subtract $\frac{5}{4}$ from $\frac{15}{4}$

$\frac{15}{4}-\frac{5}{4}=\frac{15-5}{4}=\frac{10}{4}h$

Amount of time Charles spent studying $=\frac{10}{4}h$
