Question

Please tell me how to solve by proper explanation I don't want only answer I want full explanation.​

Answer 1

It is given that Raj reads $\frac{1}{4}$ book in 1 hour.

We have to find the fraction of the book he will read in $3\frac{1}{5}$ hour

First, we will convert the mixed fraction into an improper fraction

$3\frac{1}{5} hour = \frac{16}{5} hour$

Now, we will use the unitary method

Let the fraction of the book be 'x'

1 hour = $\frac{1}{4}$  book

$\frac{16}{5}$ hour = x book

Cross multiply

$x = \frac{1}{4}\times\frac{16}{5} \\\\x=\frac{4}{5}$

So, Raj will read 4/5th of the book in $3\frac{1}{5}$  hours.
