Question

Solve the proportion.
3/6 = 7/d

Answer 1

To solve this proportion:

`(3)/(6) =(7)/(d)`

Simplify 3/6, it reduces to 1/2

`(1)/(2) =(7)/(d)`

Then do the Criss cross method

1d = 7 ×2

d=14

Hope it helps!

Answer 2

d = 14

Explanation:

We can use cross products to solve the proportion

3/6 = 7/d

3*d = 7*6

3d = 42

Divide each side by 3

3d/3 = 42/3

d = 14
