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)
On dividing a decimal by 100, the decimal point is shifted to the left by two places. Then,
= 1.72
