Question

CONSTRUCT AN ARGUMENT...

Explain how you can mental determine whether 125 x 0.9 is less than,greater than,or equal to 125.

Answer 1

By just taking a glimpse at the problem, you can immediately mentally determine whether 125 x 0.9 is greater than 125. You are multiplying 125 by a positive number that is greater than 1, therefore the value will increase. This is how anyone can mentally envision 125 x 0.9 to be greater than 125.

Answer 2

This is my argument, and my argument is less than 125. 125 × .9 = 112.5

112.5 is less than 125
