Question

Ila read 25 pages of a book containing 100 pages. Lalita read$\frac{2}{5}$of the same book. Who read less?

Answer 1

Total number of pages a book has = 100 pages

The fraction of book Ila read = $\frac{25}{100}$ = $\frac{1}{4}$

The fraction of book Lalita read = <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{2}{5}$

Now, LCM of 4 and 5 = 20.

So, $\frac{1}{4}$ = $\frac{1\times 5}{4\times 5}$ = $\frac{5}{20}$

and, $\frac{2}{5}$ = $\frac{2\times 4}{5\times 4}$ = $\frac{8}{20}$

Now, $\frac{5}{20}$ < $\frac{8}{20}$

=> $\frac{1}{4}$ < $\frac{2}{5}$

Thus, Ila read less than Lalita.
