Question

What is the p/q form of 1.3bar.

Answer 1

4/3 is the answer .
Let x= 1.3333
So 10 x= 13.33
So subtracting X from 10x we get 9x=12
=x=12/9
=x=4/3

Answer 2

The number is 1.3( bar on 3 ).

Let x = 1.3bar

Multiply by 10.

10x = 13.3bar

Subtraction the two equations,

10x - x = 13.3bar - 1.3bar

9x = 12

x = 12/3 which is in p/q form.
