The commutative property of addition states that you can change the order of addends in a sum. The associative property of addit
ion states that you can change the grouping of addends in a sum. Use an example to show how the communative property of addition and the associative property of addition apply to adding decimals
We start qt 72 degrees, 3 1/5 = 16/5 = 3.2 x 10 minutes = 32 degrees. 72 + 32 = 104 degrees. Cool Time: 4 2/7 = 30/7 = 4.28571429 x 7 minutes = 30 degrees. 104 - 30 = 74 So we went from 72 to 74 degrees, that is a 2 degree difference. This is what i got, i hope i understood the question correctly.v
