Explain how you can mentally find 8 times 45 by using distributive property. and explain

Very handy question. Don't use a calculator. That's "cheating" when you do problems like this.

Most people would break up 45 into something more easily handled but I think there is an easier way to do it. All you have to know is what 2 * 45 is.

Do you know that 2 * 45 = 90?

If you do then here's a much easier way to do the problem.

45 ( 10 - 2)

45* 10 = 450

45 * 2 = 90

450 - 90 = 360

the answer is y = 11.54

hope this : )
