Answer 1

You need to be more specific, Tammie.

But maybe this can broaden your understanding:

Think of a clock with 12 hours. The angle between hours is 30 degrees. Half of that is 15. Now you can build anything that is a multiple of 15. Like 45 = 30 + 15.

I hope that helps.

Answer 2

Your question is broad and so it would have to be the answer.

Perhaps it would help you to think of a clock as a circle, the 12 numbers are 30 degrees apart and that takes care of all multiples of 30. Plus if you know how to divided in half, you have all the multiples of 15. Say, 45 would be 30 + 15.

I hope that helps
