Question 2 – Page 50 Sonu is measuring some of his body parts. The length of Sonu’s lower arm is 2 7/10 units, and that of his upper arm is 3 6/10 units. What is the total length of his arm? Total length of Sonu’s arm = Length of Lower + Length of upper arm = 𝟐 𝟕/𝟏𝟎+ 𝟑 𝟔/𝟏𝟎 Writing in normal fractions = (2 × 10 + 7)/10+ (3 × 10 + 6)/10 = 𝟐𝟕/𝟏𝟎+ 𝟑𝟔/𝟏𝟎 Since denominator is same, we add numerators = (27 + 36)/10 = 𝟔𝟑/𝟏𝟎 Converting into mixed fraction = 𝟔 𝟑/𝟏𝟎 units
