Bill wants to multiply 7 x 9. He writes (7x5) + (7x4). Will this give him a correct answer for 7 x 9?

• Yes, because (7x5) + (7x4) is the same as 7x9.

• No, because 7x9 is 63 and (7x5) + (7x4) is 65.

Brian and Alyssa are studying multiplication and division facts families. Alyssa says she can make 4 different equations using 5, 8, and 40. What are the equations Alyssa can make?

• 5 x 8 = 40

  8 x 5 = 40

  40 ÷ 5 = 8

  40 ÷ 8 = 5

• 40 x 5 = 8

  40 x 8 = 5

  5÷8=40

  8÷5=40

• 5+8=40

  8+5=40

  40-5=8

  40-8=5

Which of the following is showing commutative property of multiplication?

• 6 x 4 = 4 x 6

• 9 x 5 = 5 x 9

• 6x2 + 6 x 2 = 6x4

Which of the statements are true? Mark all answers that apply.

• 6 x 7 = 42, so 7 x 6= 42

• 5 x 8 is 40 so 5 + 8 is 40

• 4 x 8 is 32, so 8÷4 is 32

• 3 x 6 is 18, so 18 ÷ 6 is 3

Complete the statement using the numbers below.

2 3 4 5 6 7 8 9

I know that 6 x 7 is 42, so 42 ÷ _ = 7.

Complete the statement using the numbers below.

2 3 4 5 6 7 8 9

I know that 8 x _ is 40, so 40 ÷ _ = 8.
