Answer 2

Answer:

$\frac{11}{15 } part$

Step-by-step explanation:

Given -

Sushant reads 1/3 part of book = 1 hour

To find -

How much part of book will he read in 2. 1/5 hour

Solution -

Book read in 1 hour = 1/3

Book read in 2. 1/5 hour =

$2 \frac{1}{5} \times \frac{1}{3} \\ = \frac{(2 \times 5) + 1}{5} \times \frac{1}{3} \\ = \frac{10 + 1}{5} \times \frac{1}{3} \\ = \frac{11 \times 1}{5 \times 3} \\ = \frac{11}{15}$

Hence he will read 11/15 part of book in 2. 1/5 hour
