Question

Solve for the proportion (type integer or simplified fraction)​

Answer 1

b =
`(7)/(5)` = 1.4

Explanation:

`(2b - 3 )/(5)` =
`(b - 2)/(15)`

15(2b - 3) = 5(b - 2)

30b - 45 = 5b - 10

25b = 35

5b = 7

b =
`(7)/(5)` = 1.4

Check the answer:

`(2(1.4)-3)/(5)` =
`(1.4-2)/(15)`

-
`(0.2)/(5)` = -
`(0.6)/(15)`

- 0.04 = - 0.04
