Jen wrote a number on a piece of paper. if she multiplied her number by 5 and then divided it by 2, the answer would be 30. what was jen’s number?

12. 12 multiplied by 5 is 60, 60 divided by 2 is 30

We can solve this by reverse engineering the problem.

Basically, we multiply 30 by 2 and divide it by 5, which leaves us with 12.

Jen's number is 12.
 
Hope this helps!
