Answer:
Option A. 12 + 6 + 15 = 12 + 15 + 6
Step-by-step explanation:
Cumulative property of addition says if there are three numbers a, b, c then
a + b + c = a + c + b
or a + b + c = c + b + a
Therefore, if three numbers are 12, 6, 15 then
equation that illustrates the commutative property of addition will be
12 + 6 + 15 = 12 + 15 + 6
Option A. 12 + 6 + 15 = 12 + 15 + 6 will be the correct option.
