Answer 2

Heya dear !!!



7.25 ( bar on 25)




Let X = 7.25


Then X = 7.252525 --------(1)


Multiply equation (1) by 100 we get:


100X = 725.252525 --------(2)



Subtract equation (1) from equation (2) we get:



100X = 725.252525
X = 7.252525

________________

99X = 718 [ Bar cancelled ]



X = 718/99




Hence,


7.25 ( bar on 25) is in the form of 718/99 which is in the form of P/Q.
