A survey indicated that 3 out of doctors used brand x aspirin. if 2000 doctors were surveyed, how many used brand X?

I need help understanding the problem of this math. Can somebody explain this to me.

Here's the first one.

8/64 = 2/x

Cross multiply.

8x = 128

Solve for x.

x = 128/8

x = 16

You haven't posted enough information to solve the second problem.
