Question

express 0.4 bar +0.18 bar in p/q​

Answer 1

Given :   0.4 bar +0.18 bar    , $0.\overline {4}$  +  $0.\overline {18}$    

To find : Express in p/q  form

Solution:

0.4 bar +0.18 bar

= A + B

A  = 0.4 bar  =  $0.\overline {4}$

B  = 0.18 bar =  $0.\overline {18}$

A  =   $0.\overline {4}$

10A  = $4.\overline {4}$

9A = 4

=> A = 4/9

B   =  $0.\overline {18}$

100B  = $18.\overline {18}$

=> 99B  = 18

=> B = 18/99

=> B = 2/11

4/9  + 2/11

= ( 44 + 18)/99

= 62/99

$0.\overline {4}$  +  $0.\overline {18}$   = 62/99
