Find: (i) 7/3 ÷ 2 (ii) 4/9 ÷ 5 (iii) 6/13 ÷ 7
(iv) \(4{\Large\frac{1}{3}}\) ÷ 3 (v) \(3{\Large\frac{1}{2}}\) ÷ 4 (vi) \(4{\Large\frac{3}{7}}\) ÷ 7
To divide a fraction, we will reciprocate the second fraction and then multiply the fraction with the reciprocal. If one number is a whole number then we will convert it into a fraction by using 1 as denominator.
Solution:
(i) 7/3 ÷ 2 = 7/3 × 1/2
= 7/6 (improper fraction)
Converting into mixed fraction, we get
7/6 = \(1{\Large\frac{1}{6}}\)
(ii) 4/9 ÷ 5 = 4/9 × 1/5
= 4/45
(iii) 6/13 ÷ 7 = 6/13 × 1/7
= 6/91
(iv) \(4{\Large\frac{1}{3}}\) ÷ 3
= 13/3 × 1/3
= 13/9 (Improper fraction)
Converting into mixed fraction, we get
13/9 = \(1{\Large\frac{4}{9}}\)
(v) \(3{\Large\frac{1}{2}}\) ÷ 4 = 7/2 × 1/4
= 7/8
(vi) \(4{\Large\frac{3}{7}}\) ÷ 7 = 31/7 × 1/7
= 31/49
