Answer» (i) Given (3/10) ÷ (10/3) = (3 × 3)/ (10 × 10) = (9/100) (ii) Given 4 (3/5) ÷ (4/5) First convert the given mixed fractions into improper fraction 4 (3/5) = (23/5) (23/5) ÷ (4/5) = (23 × 5)/ (5 × 4) = (23/4) = 5 (3/4) (iii) Given 5 (4/7) ÷ 1 (3/10) First convert the given mixed fractions into improper fraction (39/7) and (13/10) (39/7) ÷ (13/10) = (39 × 10)/ (7 × 13) = (390/91) = (30/7) = 4 (2/7) (iv) Given 4 ÷ 2 (2/5) First convert the given mixed fractions into improper fraction 2 (2/5) = (12/5) 4 ÷ (12/5) = (4 × 5)/12 = (20/12) = 1 (2/3) |
