How to slove 0.47 bar 7

Answer 1

Let 0.47 bar = x 


10x = 4.7 bar 


Now, As there is only one number under bar, multiply by 10 

100x = 47.7 bar 



Subtract 10x from both sides,


100x = 47.7 bar 
 -10x = -4.7 bar
___________
90x = 43
___________

x =43/90


Then, 0.47 bar is 43/90

Answer 2

Hey there!

Given

$x = 0.4 \bar{7}$

So, x = 0.4777...

Multiplying by 10 , we get

10x = 4.777

Subtracting x from 10x

10x = 4.777...
x = 0.4777......
=============
9x = 4.3

x = 43/90 .

$0.4 \bar{7} = \frac{43}{90}$
Hope helped !
