Answer: set the cross product equal.

Explanation.

A proportion is the equality of two ratios.

For example:

1        6
--- = ------
3       18

You may use the proportions to find the value of an unknown quanity

For example

1        x
--- =  ----
3       24

=> 24 = 3x

From which you can obtain: x = 24 / 3 = 8
