Question

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

Answer 1

Solve for the number of hours required by Lipika to read the book

Given, Lipika reads $1\frac{3}{4}$ hours a day and finishes an entire book in $6$ days.

Converting $1\frac{3}{4}$ into an improper fraction,
$\begin{array}{rcl}1\frac{3}{4}& =& \frac{1\times 4+3}{4}=\frac{7}{4}hrs\end{array}$

In one day, Lipika reads $\frac{7}{4}hrs$
Then in $6$ days, she reads $\frac{7}{4}\times 6=\frac{42}{4}hrs$.

Convering into mixed fraction,
$\begin{array}{rcl}\frac{42}{4}& =& \frac{40}{4}+\frac{2}{4}=10+\frac{1}{2}=10\frac{1}{2}hrs\end{array}$

Hence, Lipika required $10\frac{1}{2}$ hours to read the entire book.
