Step-by-step explanation:
(1) a) 4/5 = 4/(10/2)
= 4x(2/10)
= 8/10
= 0.8
b) 1/20 = 1/(2×10)
= 0.5/10
= 0.5 × 0.1 X
= 0.05
c) 3/160 = 3/(16×10)
= 3/16 × 1/10
= 0.1875 x 0.1
= 0.01875
(2) a) 1/5 = 1/ (10/2)
= (1×2)/10
= 2 × 0.1
= 0.2
b) 1/25 = (1/5)×(1/5)
= 1/(100/4)
= 0.2 × 0.2 (OR) = (1x4) / 100
= 0.04
= 4/100 =
0.04
c) 1/5+1/25 = 0.2 +0.04 = 0.24
(OR)
LCM of 5,25 = 25 1/5 + 1/25 = (5+1)/25
= 6/25
= 0.24
