Question

Represent 0.625 where bar is on 5 in the form of p/q

Answer 1

Answer:

0.625 ( bar on 25)

Let X = 0.625

Then X = 0.62525 -------(1)

Multiple equation (1) by 10 we get,

10X = 6.2525 --------(2)

Again multiple equation (2) by 100 we get,

1000X = 625.2525 ------(3)

Subtract equation (2) from equation (3)

1000X = 625.2525

10X = 6.2525

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

990X = 619

X = 619/990 [ P/Q form ]

Hence,

0.625 ( bar on 25) is of the form of 619/990 which is in the form of P/Q.
