Which is an example of the Associative Property
a. 5 x (2 x 6) = (5 x 2 ) x 6
b. 5 x (2 + 6) = (5 x 2 ) + (5 x 6)
c. 5 x 2 x 6 = 60
a. 5 x (2 x 6) = (5 x 2 ) x 6
34 x 4

A pizza shop usually sells 40 pizzas each weekend day and 25 pizzas each week day. How many pizzas do they sell in a week?
40 x 2 = 80
25 x 5 = 125
80 + 125 = 205 pizzas
Which equation shows the commutative property?
35 x 15 = 15 x 35
(35 x 15) x 8 = 35 x (15 x 8)
35 x 15 = (30 x 15) + (5 x 15)
35 x 1 = 35
35 x 15 = 15 x 35
(8 + 10) x 7
126
3 3/4 x 1/8
15 / 32
27 x 381
The estimate is 30 x 400 = 12,000
What is 305 added to the product of 10 x 5?
355
Which equation shows the distributive property?
(8 x 4) x 12 = 8 x (4 x 12)
12 x 8 = (10 x 8) + (2 x 8)
12 x 8 = 96
12 x 8 = 8 x 12
12 x 8 = (10 x 8) + (2 x 8)
(50 + 8) x 40
2320
5 2/4 x 1 1/2
8 1/4
551 x 290
The estimate is 600 x 300 = 180,000
If students eat 2/3 of 90 apples, how many apples are not eaten?
