Ex 2.3, 4 Which is greater: (i) 2/7 of 3/4 or 3/5 of 5/8 2/7 of 3/4 = 2/7 ร 3/4 = (2 ร 3)/(7 ร 4) = 3/(7 ร 12) = ๐/๐๐ 3/5 of 5/8 = 3/5 ร 5/8 = (3 ร 5)/(5 ร 8) = ๐/๐ Now, We have to find greater of 3/14 & 3/8 To compare fractions, we make denominator equal. Common denominator = LCM of 14 & 8 = 2 ร 2 ร 2 ร 7 = 8 ร 7 = 56 So, 3/14 = 3/8 = โด 21/56 > 12/56 i.e. 3/8 > 3/14 โด 3/5 of 5/8 > 2/7 of 3/7 So, ๐/๐ of ๐/๐ is greater.
