Question

Solve the proportion.
20/13 = 60/d
d=

Answer 1

`d = 39`

Explanation:

1) Multiply both sides by d.

`(20)/(13) d = 60`

2) Simplify 20/13d to 20d/13.

`(20d)/(13) = 60`

3) Multiply both sides by 13.

`20d = 60 * 13`

4) Simplify 60 × 13 to 780.

`20d = 780`

5) Divide both sides by 20.

`d = (780)/(20)`

6) Simplify 780/20 to 39.

`d = 39`

Therefor, the answer is d = 39.
