Question

Express 0.235 bar in the form of p/q The bar is only on 3and5

Answer 1

Let x= 0.2353535....
100x = 23.535353.....
10000x = 2353.535353...
10000x - 100x = 2353.5353.. - 23.5353...
9900x = 2330
X = 2330/9900
= 233/990 answer
Or
100x - x = 23.5353.. - 0.2353....
99x = 23.30 or 2330/100 or 233/10
X = 233/10 x 99
= 233/990
