Explaining cross products the following three proportions can all be used to solve the problem about caroline's salary. explain why the solutions to each proportion are the same. 36/4=x/7 4/36=7/x 36/x=4/7

All 3 of these would result in the same answer. You can see this by looking at the cross products that would be created for each of them.

In each proportion, you would get a variation of 37 times 7 = 4 times x, when you multiply the numerator of the first by the denominator of the second and the denominator of the first by the numerator of the second.

Each proportion is written so the units are in the corresponding positions. The cross products of all the proportions result in the equation 4x = 252, which results in x = 63.

Have a Wonderful Day!
