Question

How to express 0.685 bar in the form of p/q

Answer 1

Answer:

Step-by-step explanation:

Let x = 0.685685685.......... -1

Then 1000x = 685.685685........ -2

Subtracting eq 1 from eq 2

1000x-x = (0.685685.....)-(685.685685.....)

=> 999x = 685

=> x = 685/999

Hence , the required p/q form is 685/999.
