Question

Sean wrote a number on a piece of paper.
If he multiplied his number by 5 and then divided by 2,
the answer would be 30. What was Sean’s number?

Answer 1

The Sean's number is x. Formulate the equation:

x * 5 : 2 = 30
5x = 30 * 2
5x = 60
x = 60 : 5
x = 12

Answer: the Sean's number is 12.
