Frequently asked questions

How do I know if the problem is direct or inverse proportion?

If two quantities change together in the same direction, it is usually direct proportion; if one rises while the other falls, it is often inverse proportion.

Why use three known values?

Because the goal is to solve the fourth unknown value from a four-part proportion setup.

Can proportion results be decimals?

Yes. The solved value does not need to be a whole number.
