Dear Student

(i) 0.2 × 6

Solution:- We have,

= (2/10) × 6

= (12/10)
On dividing a decimal by 10, the decimal point is shifted to the left by one place. Then,

= 1.2

(ii) 8 × 4.6

Solution:- We have,

= (8) × (46/10)

= (368/10)
On dividing a decimal by 10, the decimal point is shifted to the left by one place. Then,

= 36.8

(iii) 2.71 × 5

Solution:- We have,

= (271/100) × 5

= (1355/100)
On dividing a decimal by 100, the decimal point is shifted to the left by two places. Then,

= 13.55

(iv) 20.1 × 4

Solution:- We have,

= (201/10) × 4

= (804/10)
On dividing a decimal by 10, the decimal point is shifted to the left by one place. Then,

(v) 0.05 × 7

Solution:- We have,

= (5/100) × 7

= (35/100)
On dividing a decimal by 100, the decimal point is shifted to the left by two places. Then,

= 0.35

(vi) 211.02 × 4

Solution:-
We have,

= (21102/100) × 4

= (84408/100)
On dividing a decimal by 100, the decimal point is shifted to the left by two places. Then,

= 844.08

(vii) 2 × 0.86

Solution:- We have,

= (2) × (86/100)

= (172/100)
