6. Isha read 25 pages of a book containing 100 pages. Nagma read ½ of the same book. Who read less? 
Solution: 
 
No. of pages in the book = 100 
We know that 
Fraction of book Isha read = (25/100) ÷ (25/25) = 1/4 by dividing both numerator and denominator by HCF of 25 
and 100 
So the fraction of book Nagma read = 1/2 
By comparing 1/4 and 1/2 we get the LCM of 4 and 2 = 4 
Now convert the fraction into equivalent fraction having denominator as 4 
1/4 × 1/1 and 1/2 × 2/2  
1/4 < ½ 
 
Hence, Isha read less.
