Question

1/4(r-5/2)=1/8 i need an answer cant figure it out

Answer 1

`(1)/(4)(r - (5)/(2)) = (1)/(8)`

The LCD of both fractions is 8, so multiply both sides by 8.


`8 * (1)/(4)(r - (5)/(2)) = 8 * (1)/(8)`


`2(r - (5)/(2)) = 1`

Distribute the 2 on the left side.


`2r - 5 = 1`


`2r = 6`


`r = 3`

Answer 2

1/4(r - 5/2) = 1/8
Divide both sides by 1/8 :0
2(r - 5/2) = 1
r - 5/2 = 1/2
r = 1/2 + 5/2 = 6/2

r = 3 Answer
