8+ 7 = 15 choose the related addition sentence that shows the commutative property of addition. a. 15 – 8 = 7 b. 14 + 1 = 15 c. 7 + 8 = 15 d. 15 = 8 + 7

For this case, we have the following generic expression:

The commutative property of the addition states that the order of the addends does not alter the sum, therefore the previous expression above can be written as:

Thus the expression, applying the commutative property, can be written as:

Option c
