Q1.

Example 1: A farmer had 5 grandchildren. She distributed ²⁄₃ acre of land to each of her grandchildren. How much land in all did she give to her grandchildren?

Answer

Five equal shares of ²⁄₃ acre each.

5 × 2/3 = 2/3 + 2/3 + 2/3 + 2/3 + 2/3
= 10/3
= 3 1/3 acres

Why it happens: ten one-third pieces are handed out in all. Three thirds make one acre, so ten thirds make 3 whole acres and one third left over.

Q2.

Example 2: 1 hour of internet time costs ₹8. How much will 1 ¹⁄₄ hours of internet time cost?

Answer

First change the mixed fraction into an improper fraction.

1 1/4 hours = 5/4 hours
Cost = 5/4 × 8
= (5 × 8) ÷ 4
= 5 × 2
= ₹10

Tip: divide first (8 ÷ 4 = 2), then multiply (5 × 2 = 10). Smaller numbers, fewer mistakes.
