## Question

Lipika reads a book for \begin{align} 1\frac{3}{4}\end{align} hour every day. She reads the entire book in $$6$$ days. How many hours in all were required by her to read the book?

## Text Solution

What is known?

Lipika reads for \begin{align}1\frac{3}{4}\end{align}hours every day and read the entire book in $$6$$ days.

What is unknown?

Total hours required by her to complete the book.

Reasoning:

In a day she reads for \begin{align}1\frac{3}{4}\end{align} hours so for calculating $$6$$ days we can simply multiply \begin{align}1\frac{3}{4}\end{align} hours by $$6$$.

Steps:

\begin{align} \text{No. of hours taken by Lipika to read a book everyday}=1\frac{3}{4}{\rm{ hour }} = \frac{7}{4}\end{align}

No. of days taken to read the entire book $$= 6 \rm \,days$$

\begin{align} \text{Total no. of hours required by her to read the book}= \frac{7}{4} \times 6 = \frac{{42}}{4}{\rm\,{ hours }} = 10\frac{1}{2}\end{align}

Thus, \begin{align} 10\frac{1}{2}\end{align} hours in all were required by Lipika to read the book.
