Question

There were 5 people who bought tickets to a football game. They bought 3 tickets each. How many tickets were bought in all?

Answer 1

5 people times 3 tickets each
5 times 3 = 15

15 tickets in all

Answer 2

So basically you want to say,

five people who each bought 3 tickets

Or, 

five groups of 3 tickets.

So five groups of 3 tickets would be,

3 + 3 + 3 + 3 + 3,

or 3 * 5.

3 * 5 = 15.
