As per the question, Ila read 25 pages out of 100 pages.
Fraction of the pages read by Ila=25100
25 is the common factor of both 25 and 100, so divide the numerator and denominator by 25, we get
So, Ila read 14thpart of book.
Given that Lalita read 25th part of book
To compare both the fractions, let us convert them into like fractions.
LCM of the denominators of 14 and 25 , i.e., LCM of 4 and 5 is 20.
Now, writing 14 and 25 as equivalent fractions having same denominator which is 20, we get
14=1×54×5=520 and 25=2×45×4=820
On comparing the numerators, we have
5 < 8
Therefore, Ila read less than Lalitha.
