Question

express 0.3 (there is a bar on 3) in the form of 1/2

Answer 1

let 0.333333 = x................(1)

multiply the (1) by 10

= 10x = 3.333333................(2)

= subtarct(1) from (2)

= 9x = 3

= x = 1/3.

Answer 2

let X = 0.3 bar
X=0.333..... - Eq. 1
Multiply by 10
10x=3.333... - Eq. 2
Subtract Eq.1 from Eq.2
10x-X = 3.333-0.333
9x = 3
X = 3/9
X = 1/3 This is the answer
I don't think that 0.3 bar can be written in the form of 1/2
