Question

(3 x 5) x 9 = 3 x (5 x 9)


True
False

Answer 1

True because no matter what group you multiply first it will be the same answer example 1 x(2 x 3) = (1 x 2) x 3 so using PEMDAS in the parenthesis you multiply 2 x 3 = 6 x 1 = 6 and 1 x 2 = 2 x 3 = 6 so either way it works   

Answer 2

The answer is true here's the reasons: (3 x 5) x 9 is what i started to solve first.

The first thing i did was i took the 3 and multiply it by 5 which gave me 15 then multiply it by 9 it gave me 135. So that was the first side done

The second part on 3x (5 x 9) I took the 5 and multiply it by the 9 which is 45 and then multiply it by 3 which gave me the same answer as the other side. Which would look like this 135=135

So your answer should be true hope this helps. :)
