1.
Choose the correct addition and subtraction fact family using 6, 17, and 11. a. 17 - 11 = 6, 17 - 6 = 11 b. 6 + 11 = 17, 17 - 6 = 11 c. 15 + 8 = 7, 7 + 8 = 15 d. 11 + 17 = 6, 11 - 6 = 17

#### Solution:

Fact family is a group of related facts using the same set of numbers.

The addition and subtraction fact family of 6, 17, and 11 is
6 + 11 = 17, 11 + 6 = 17, 17 - 6 = 11, and 17 - 11 = 6.

So, the correct addition and subtraction fact family using 6, 17, and 11 is 6 + 11 = 17 and 17 - 6 = 11.

2.
Which is the correct addition and subtraction fact family using 19, 5, and 14? a. 14 + 5 = 19, 19 - 14 = 5 b. 5 + 14 = 21, 19 - 14 = 5 c. 5 + 19 = 14, 14 - 5 = 19 d. 14 + 19 = 33, 19 - 5 = 14

#### Solution:

Fact family is a group of related facts using the same set of numbers.

The addition and subtraction fact family of 19, 5, and 14 is
5 + 14 = 19, 14 + 5 = 19, 19 - 5 = 14, and 19 - 14 = 5.

So, the correct addition and subtraction fact family using 19, 5, and 14 is 14 + 5 = 19 and 19 - 14 = 5.

3.
Which number sentence can be used to check your answer for   23 + 8 = 31? a. 31 - 23 = 9 b. 31 - 8 = 23 c. 23 - 8 = 31 d. 31 + 8 = 23

#### Solution:

The subtraction facts for the number sentence 23 + 8 = 31 are 31 - 23 = 8 and 31 - 8 = 23.

So, the number sentence 31 - 8 = 23 can be used to check the answer for 23 + 8 = 31.

4.
Which number sentence is in the fact family for 24, 42, 18? a. 42 + 24 = 18 b. 24 - 18 = 42 c. 24 - 18 = 6 d. 24 + 18 = 42

#### Solution:

Fact family is a group of related facts using the same set of numbers.

The addition and subtraction fact family of 24, 42, and 18 is
18 + 24 = 42, 24 + 18 = 42, 42 - 24 = 18, and 42 - 18 = 24.

So, the number sentence 24 + 18 = 42 is in the fact family for 24, 42 and 18.

5.
Which number sentence is not in the fact family for 15, 3, 18? a. 18 - 15 = 3 b. 18 - 3 = 15 c. 15 + 18 = 33 d. 15 + 3 = 18

#### Solution:

Fact family is a group of related facts using the same set of numbers.

The addition and subtraction fact family of 15, 3, and 18 is
3 + 15 = 18, 15 + 3 = 18, 18 - 3 = 15, and 18 - 15 = 3.

So, the number sentence 15 + 18 = 33 is not in the fact family for 15, 3, and 18.

6.
Which multiplication fact could be used to find 49 ÷ 7? a. 8 × 9 = 72 b. 7 × 7 = 49 c. 5 × 6 = 30 d. 49 × 7 = 343

#### Solution:

49 ÷ 7
[Original expression.]

49 is dividend, 7 is divisor, and 7 will be the quotient.
[49 ÷ 7 = 7.]

Dividend becomes product, divisor and quotient become factors for multiplication fact.

So, the multiplication fact for 49 ÷ 7 is 7 × 7 = 49.

7.
Which multiplication fact could be used to find 10 ÷ 5? a. 4 × 5 = 20 b. 2 × 5 = 10 c. 2 × 4 = 8 d. 10 × 5 = 50

#### Solution:

10 ÷ 5
[Original expression.]

10 is the dividend, 5 is divisor, and 2 will be quotient.
[10 ÷ 5 = 2.]

Dividend becomes product, divisor and quotient become factors for multiplicating fact.

So, the multiplication fact for 10 ÷ 5 is 2 × 5 = 10.

8.
Which multiplication fact could be used to find 16 ÷ 4? a. 2 × 8 = 16 b. 8 × 2 = 16 c. 16 × 4 = 64 d. 4 × 4 = 16

#### Solution:

16 ÷ 4
[Original expression.]

16 is dividend, 4 is divisor, and 4 will be the quotient.
[16 ÷ 4 = 4.]

Dividend becomes product, divisor and quotient become factors for multiplicating fact.

So, the multiplication fact for 16 ÷ 4 is 4 × 4 = 16.

9.
Which multiplication fact could be used to find 32 ÷ 4? a. 8 × 4 = 32 b. 16 × 2 = 32 c. 32 × 1 = 32 d. I don′t know.

#### Solution:

32 ÷ 4
[Original expression.]

32 is dividend, 4 is divisor, and 8 will be the quotient.
[32 ÷ 4 = 8.]

Dividend becomes product, divisor and quotient become factors for multiplicating fact.

So, the multiplication fact for 32 ÷ 4 is 8 × 4 = 32.

10.
Which multiplication fact could be used to find 60 ÷ 5? a. 15 × 4 = 60 b. 12 × 5 = 60 c. 10 × 6 = 60 d. 30 × 2 = 60

#### Solution:

60 ÷ 5
[Original expression.]

60 is dividend, 5 is divisor, and 12 will be the quotient.
[60 ÷ 5 = 12.]

Dividend becomes product, divisor and quotient become factors for multiplication fact.

So, the multiplication fact for 60 ÷ 5 is 12 × 5 = 60.
