You can solve the following proportion by cross multiplying. What will the equation be after you cross multiply? 3 x= 9 • 15
3 x = 15
3 • 15 = 9 X
15 = 9 X

=====================================

Explanation:

Anything in the form A/B = C/D will cross multiply to A*D = B*C

In this case, A = 3, B = 9, C = x and D = 15

So that's why 3/9 = x/15 cross multiplies to 3*15 = 9*x
