Question

Is for over two and 20/6 proportions

Answer 1

To find out if fractions are proportional you cross multiply.

4 20
-- x ---
2 6

4 x 6 = 24

2 x 20 = 40

If they are alike then they are proportional, if they are not then they are NOT proportional.

Answer 2

no they're not proportional, and it's four*.
4/2 = 2
20/6 = 3.333333333334 or 3 1/3
