Question

change the denominators into Powers of 10 and write the decimal forms .
a)4/5
b)1/20
c)3/160
change into the decimal forms
a)1/5
b)1/25
c)1/5+1/25​

Answer 1

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
