Question

Brandon says 4 x 800 is greater than 8 x 4,000. Renee says 4 x 800 is less than 8 X 4,000.A. Without calculating the answer, explain how to use place-value strategies or the Associative Property to find which is greater

Answer 1

We have two multiplications:

4*800

And

8*4000

We have that 8 is higher than 4, and 4000 is higher than 800. This means that the second one is greather, which means that Renee is correct
