Answer 2

Given :  0.72 bar (bar on 7and 2)  $0.\overline{72}$

To Find :  express  in the form of p/q

p + q  , p = q  ,  p * q  , p/q

Solution:

N = $0.\overline{72}$

100N  =  $72.\overline{72}$

=> 99N  = 72

=>  33N = 24

=> 11N = 8

=> N = 8/11

Comparing with p/q

p = 8

q = 11

p + q = 8 + 11 = 19

p - q  = 8 - 11 = - 3

p * q  = 8 * 11  = 88

p/q  = 8/11
