Claire correctly solved the proportion StartFraction x over 4 EndFraction = StartFraction 36 over 16 EndFraction for x by using cross products to get the equation 16 x = 144 and then dividing both sides by 16 to get x = 9. She showed that she can use cross products to solve the proportion because she gets the same answer if the solves it as shown.

Answer 1

crap. Use real math, ok?

no idea what "as shown" is

and you didn't even ask a question.

Answer 2

What the hell is this?
