Answer 2

Answer:

Krishna read more pages of the same book than Ila

Step-by-step explanation:

$\sf No. \: pages\: Ila \: read = \frac{25}{100} \: pages \: of \: book$

$\sf \frac{25 \div 25}{100 \div 25} = \frac{1}{4} \: pages \: of \: the \: book$

$\sf No. \: pages \: Krishna \: read = \frac{2}{5} \: pages \: of \: book$

Now, find the LCM of their denominators

2 | 4, 5

2 | 2, 5

5 | 1, 5

1, 1

LCM of 4 and 5 = 2 × 2 × 5

= 20

$\sf \frac{1 \times 5}{4 \times 5} = \frac{5}{20} \: , \: \frac{2 \times 4}{5 \times 4} = \frac{8}{20}$

Now, compare

$\sf \frac{8}{20} > \frac{5}{20} = \frac{1}{4} > \frac{2}{5}$
