Q1) Multiply :

(i) 5.6 and 8

(ii) 38.46 and 9

(iii) 0.943 and 62

(iv) 0.0453 and 35

(v) 7.5 and 2.5

(vi) 4.23 and 0.8

(vii) 83.54 and 0.07

(viii) 0.636 and 1.83

(ix) 6.4564 and 1000

(x) 0.076 and 100

Solution:

(i) 5.6 x 8 = 44.8

(ii) 38.46 x 9 = 346.14

(iii) 0.943 and 62

0.943 x 62 = 58.466

(iv) 0.0453 x 35 = 1.5855

(v) 7.5 x 2.5 = 18.75

(vi)4.23 and 0.8

Since 423 x 0.8 = 3384

4.23 x 0.8 = 3.384

(vii) 83.54 and 0.07

Since 8354 x 7 = 58478

83.54 x 0.07 = 5.8478

(viii) 0.636 x 1.83 = 1.16388

(ix) 6.4564 x 1000

Since 64564 x 1000 = 64564000

6.4564 x 1000 = 6456.4000

= 6456.4

(x) 0.076 and 100

Since 76 x 100 = 7600

0.076 x 100 = 7.600 = 7.6
