Question

1.3 bar in the form of p/q

Answer 1

Let x
1.3 bar = x equation no. 1
Multiply both sides by 10
13.3 bar = 10x. equation no.2
From 2nd - 1st
(13.3-1.3) = (10x-x)
12 = 9x
12 ÷ 9 = x
4 / 3 = x

Answer 2

$\textbf{Solution:}$

Let x = 1.33333.....(1)

10x = 13.33333......(2)

On subtracting (1) from (2) , we have ;

10x - x = 13 - 1

=> 9x = 12

=> x = $\frac{12}{9} = \frac{4}{3}$

Therefore, 1.3 bar = $\frac{4}{3}$
