Question

If priya reads 1/5 of the book in 1 hour how much book will she read in 3 3/4 hours ?

Answer 1

Part of book read in 1 hour = $\frac{1}{5}$

Part of book read in 3$\frac{3}{4}$ hours = $\frac{1}{5}$ × 3$\frac{3}{4}$

= $\frac{1}{5}$ × $\frac {4 × 3 + 3}{4}$

= $\frac{1}{5}$ × $\frac{15}{4}$ = $\frac{15}{20}$

:. $\frac{15}{20}$ part is read .
