Advanced Math practice question

Answer: 3

12/x − 1 = 3, so 12/x = 4 and x = 3.

Common wrong answers

If you answered 4

4 is each person's share in dollars (12/x), not the number of people.

If you answered 6

6 comes from 12/x = 2, subtracting 1 instead of adding it.

If you answered 36

36 multiplies 12 by 3 instead of dividing by 4.
