Question

Please help!! Which one is it?

Answer 1

A. Commutative property of addition looks like

a+b = b+a.

We can see that (-7/8) and 4/5 changed their places , so

we have Commutative Property of Addition here.

`(3)/(5) + (-(7)/(8)) + (4)/(5) = (3)/(5) + (4)/(5) + (-(7)/(8))`

B. Addition property of equality (not this one)

if a=b, then a+c = b+c

C. Associative property of addition (not this one)

a+(b+c) = (a+b)+c

D. Identity property of addition. (not this one)

a+0=a

Answer is A.
