Question

represent 0.35bar7 in p/q

Answer 1

Heya !!!



0.357 ( bar on 7)



Let X = 0.357



Then X = 0.3577 -----(1)


Multiply equation (1) by 100 we get,



100X = 35.77 ------(2)



Again multiply equation (2) by 10 we get,



1000X = 357.77 -------(3)



Subtract equation (2) from equation (3) we get,




1000X = 357.77

100X = 35.77

---------------------

900X = 322



X = 322/900 = 161/450



Hence,


0.357 ( bar on 7) is in the form of 161/450 which is in the form of P/Q.
