Question

How can 12×50 help you find 12×49?

Answer 1

It will help because than you could subtract 12 to get the answer of 12 x 49. You just have to make sure you do the problem right.

Answer 2

Well 12 times 50 is 600 
and 12 times 49 is 588 so you are rounding 49 to 50 to make it easier to solve the question
and 588 rounds to 600 so if one answer is 1 more than the answer than the answer would be 2 less than the the another number
it could also be the other way around so it could be 2 more than the the another number
