28: 42=x: 54 what is the value of x.

We need to think, 28 / 42 = x / 54.

We need to do a proportion for this problem!

First, line up both fractions, then put a equal sign between both fractions.

28 / 42 = x / 54.

We multiply in a diagonal and then we divide by the one without a diagonal.

28 and 54 are a diagonal.

We multiply both numbers!

54 x 28 = 1,512.

Then, we divide by 42.

1,512 / 42 = 36.

Therefore, x = 36.
