Which of the following equations uses the commutative property of addition to rewrite 1/3 + 2/5?

a
1/3+2/5=5/15+6/15

b
11/15-2/5=1/3

c
2/3+1/5=13/15

d
2/5+1/3=11/15

The commutative property states that you can invert the order of the terms of a sum:

So, if you start with

Applying the commutative property you'll get

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

"a" determine whether sage found the correct quotient. show your work
