Question

Find:

(i) 4.2 x 3.5
(ii) 6.25 x 0.5
(iii) 1.2 x 0.15
(iv) 0.08 x 0.5
(v) 101.01 x 0.01
(vi) 20.05 x 4.8

Answer 1

(i) 4.2 x 3.5

(ii) 6.25 x 0.5

Hence 6.25 x 0.5 = 3.125

Place the decimal point in product so decimal point is put from right side = 1 + 1 = 2

So 4.2 x 3.5 = 14.70

= 14.7

(iii) 1.2 x 0.15

So, 11.2 x 0.15 = 1.68

(iv) 0.08 x 0.5

Hence 0.08 x 0.5 = 0.040 = 0.04

(v) 101.01 x 0.01

(vi) 20.05 x 4.8

Hence, 20.05 x 4.8 = 96.240

= 96.24
