Solution
Fraction of books in Asha’s shelf =5/6 Fraction of books in Samuel’s shelf =2/5 We compare the fractions to find whose shelf is more full. LCM of 5 & 6 is 30 5/6 =5×5/5×6 =25/30
2/5 =2×6/5×6 =12/30 25/30>12/30 ⇒ 5/6>2/5
So, Asha’s shelf has more books and is more full. 5/6−2/5 =5×5/6×5−2×6/5×6 =25/30−12/30 =13/30
