Question

Solve the following proportion.
х
42
35
10

Answer 1

12

Explanation:

The proportion is equal to
`(x)/(10)=(42)/(35)`

We can simplify the right side by dividing by 7/7 to get the right side equal to 6/5. Now we can cross-multiply to get

`60=5x`

Dividing both sides by 5, we have the answer as

`x=12`
