Question

100.28 bar in fractional form​

Answer 1

Step-by-step explanation:

. Express 0.18 as vulgar fraction.

Solution:

x = 0.18

Multiply both sides by 10 (Since number of digits without bar is 1)

10x = 1.8

10x = 1.88…… ---------- (i)

10 × 10x = 1.88…… × 10 (Since number of digits having bars is 1)

100x = 18.8….. ------------- (ii)

Subtracting (i) from (ii)

100x - 10x = 18.8 - 1.8

90x = 17

x = 17/90

Therefore, the vulgar fraction = 17/90

2. Express 0.23 as vulgar fraction.

Solution:

x = 0.23

Multiply both sides by 10 (Since number of digits without bar is 1)

10x = 2.3

10x = 2.33…… ---------- (i)

10 × 10x = 2.33…… × 10 (Since number of digits having bars is 1)

100x = 23.3….. ------------- (ii)

Subtracting (i) from (ii)

100x - 10x = 23.3 - 2.3

90x = 21

x = 21/90

x = 7/30

Therefore, the vulgar fraction = 7/30
