Solution 1

The problem states that the ratio of a to b is 5 to 2, or a/b = 5/2.

We also know that a = -20.

We can substitute -20 for a in the ratio to find the value of b.

So, -20/b = 5/2.

To solve for b, we can cross-multiply to get -40 = 5b.

Then, divide both sides by 5 to get b = -40/5 = -8.
