Question

Explain how you can mentally find 8×45 by using the distributive property

Answer 1

One way to approach this would be to rewrite 8 as (10-2).

Then we are to find 45(10-2), which is 450 - 90 = 360 (answer)

Answer 2

First you multiply 8 by 40 which is 320, and th n you multiply 5 by 8 which is 40 making the total 360
