Question

Express 0.6 + 0.7bar + 0.47bar in the form p by q where p and q are integers and q is not = 0​

Answer 1

Answer:

Let x=0.666.......  (1)

Multiply equation (1 by 10

10x = 6.666.......  (2)

Subtract equation (1) from (2)

x=6/9

Similarly 0.7bar =7/9 and 0.47bar = 47/99.

6/9+7/9+47/99=190/99
