Question

Narendra reads $\frac{1}{4}$ of a short novel in 1 hour. What part of the book will he have read in 2$\frac{1}{2}$ hours?

Answer 1

The part of the novel read by Narendra in 1 hour = $\frac{1}{4}$

So the part of the novel read by him in $2\frac{1}{2}$ hours = $2\frac{1}{2}\times \frac{1}{4}=\frac{5}{2}\times \frac{1}{4}=\frac{5}{8}$
So, Narendra would read $\frac{5}{8}$ part of the novel is $2\frac{1}{2}$ hours.
