Answer:

8 and 132 over 999.(option b)

Explanation:

8.132132132......

We have to convert into rational number

Let x=8.132132132.... equation (1)

multiply (1) equation by 1000 both sides

1000x= 8132.132132... equation (2)

subtracting equation (1) from (2)

1000x- x= 8132.132132...- 8.132132....

999x= 8124

x=
(8124)/(999)

x= 8
(132)/(999)

Hence, the correct answer is 8 and 132 over 999

8 would become the whole number, since there are 3 repeating numbers you would put those over 999.

So you would get 8 and 132/999
