Susan bought 6 boxes of girl scout cookies, Jacob bought 3 boxes and Nick bought 10 boxes. What two equivalent expressions can be used to find the total number of girl scout cookie boxes that were purchased?

(6 x 3) x 10 = 6 x ( 3 x 10)

6 (3 x 10) = 6(3) + 6(10)

6 + (3 + 10) = (6 + 3) + 10

6 + 3 = 10 + 63

Trish ran 6 laps each day for 4 days. Each lap is 1/4 mile of a mile. Which property will find the number of miles she ran

Commutative; 6 x 4 = 4 x 6

Commutative; 1/4 x 6 = 4 x 1/4

Associative; 1/4 (6)(4) = 1/4 (4)(6)

Identity; 1/4 + 1 = 1141
