Given:

Lipika reads a book for $1\frac{3}{4}$ hours everyday. She reads the entire book in 6 days.

To do:

We have to find the number of hours required by her to read the book.

Solution:

Number of hours Lipika reads a book everyday$=1\frac{3}{4}$

$=\frac{1\times4+3}{4}$

$=\frac{7}{4}$

Number of days taken to read the entire book $=6$

Total number of hours required by her to read the complete book$=(\frac{7}{4})\times6$

$=\frac{42}{4}$

$=\frac{21}{2}$

$=10\frac{1}{2}$

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