Q.3 Multiply and reduce to lowest form and convert into a mixed fraction:

(i) 7×(3/5)
(ii) 4× (1/3)
(iii) 2×(6/7)
(iv) 5× (2/9)
(v) (2/3) × 4
(vi) (5/2) ×6
(vii) 11× (4/7)
(viii) 20×(4/5)
(ix) 13×(1/3)
( x) 15 ×(3 /5)


Answer :

(i)7×(3/5) = 21/5 = \(4\frac{1}{5} \)
(ii) 4× (1/3) = 4/3 = \( 1\frac{1}{3} \)
(iii) 2×(6/7) =12/7 =\( 1\frac{5}{7} \)
(iv) 5× (2/9) = 10/9 = \(1\frac{1}{9} \)
(v) (2/3) × 4 = 8/3 =\(2\frac{2}{3} \)
(vi) (5/2) ×6 = 30/2 =\(\frac{30÷2}{2÷2} = 15/1=15 \)
(vii) 11× (4/7) = 44/7 =\( 6\frac{2}{7} \)
(viii) 20×(4/5) = (20/1) × (4/5)= (80/5)= 16
(ix) 13×(1/3) = 13/3 = \(4\frac{1}{3} \)
(x) 15 ×(3 /5) = 45 /5 = 15
