A survey indicated that 3 out of 5 doctors use brand X aspirin.

If 2000 doctors were surveyed, how many used brand X?

can somebody tell me is this the right answer yes or no,
2000/ 3/5 400*5/3*5
400/3 133 1/3

    No.

    You can't have 1/3 of a doctor.

    3/5 = x/2000

    Cross multiply and solve for x.
