Question

Express 0.6bar+0.7bar+0.47

Answer 1

First convert 0.6bar into fraction
Let x => 0.6bar
10x => 6.6bar
On subtracting
9x => 6
X => 6/9
2/3

NOW CONVERT 0.8bar into fraction
Let x => 0.7bar
10x => 7.7bar
On subtracting
9x => 7
X => 7/9

Now add 0.7bar + 0.6bar +0.47
6/9+7/9+47/100
(600+700+423)/900
1723/900
1.91444bar (only four is in bar)
