## 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} \begin{Bmatrix}\text{No. of hours taken by Lipika }\\ \text{to read a book everyday}\end{Bmatrix} \end{align}

\begin{align} =1\frac{3}{4}{\rm{ hour }} = \frac{7}{4}\end{align}

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

$$\begin{Bmatrix} \text{Total no. of hours required } \\ \text{ by her to read the book} \end{Bmatrix}$$

\begin{align} &= \frac{7}{4} \times 6 \\[0.5mm] &= \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.
