5. Which equation below models the commutative property?

a. 10 + 2 +5 = 2 +5 + 10

b. 12 - 4- 1 = 4 - 12 - 1

c. (10 X 2) X 5 = 10 X (2 X 5)

d. 10 ÷ 2 ÷ 5 = 5 ÷ 2 ÷ 10 

a. 10 + 2 +5 = 2 +5 + 10

200

Which equation below models the associative property?

a. (2 ÷ 3) ÷ 5 = 2 ÷ (3 ÷ 5)

b.  2 x 3 x 4 = 4 x 3 x 2

c.  (2 - 3) - 10 = 2 - (3 - 10)

d.  2 + (5 + 7) = (2 + 5) + 7

d. 2 + (5 + 7) = (2 + 5) + 7

300

Use the commutative property to write and expression equivalent to:

2 + 7 + 9

9 + 7 + 2 

9 + 2 + 7

2 + 9 + 7

7 + 2 + 9

7 + 9 + 2
