Question 2.

Match the equal expressions.

Answer:

Matched the equal expressions as

Explanation:

Matching the equal expressions as

24 Ã· 2 = (20 Ã· 2) + (4 Ã·Â 2),

24 is written as (20 + 4) Ã· 2.

36 Ã· 3 = (30 Ã· 3) + (6 Ã· 3),

36 is written as (30 + 6) Ã· 3.

39 Ã·Â 3 = (30 Ã·Â 3) + (9 Ã·Â 3),

39 is written as (30 + 9) Ã· 3.

26 Ã· 2 = ( 20 Ã· 2) + (6 Ã· 2),

26 is written as (20 + 6) Ã· 2.

Question 3.

Nell draws the array below to find the answer to 24 Ã· 2. Explain Nellâ€™s strategy.

Answer:

Nell’s strategy is 24 Ã· 2 = (12 Ã· 2) + (12 Ã· 2),

6 + 6 = 12, So, 24 Ã· 2 = 12,

Explanation:

To find answer for 24 Ã· 2 Nell draws an array his strategy is he divided 24 as 12 + 12 then has divided with 2, So equation for Nell’s drawing is

24 Ã· 2 = (12 Ã· 2) + (12 Ã· 2), 6 + 6 = 12.

Therefore 24 Ã· 2 = 12.

Complete the equations below to solve 22 Ã· 2 = __11___.

Answer:

22 Ã· 2 = 11,

Explanation:

We solve 22 Ã· 2 as below first we write 22 as 20 + 2

and divide by 2,

(20 + 2) Ã· 2 = (20 Ã· 2) +(2 Ã· 2) = 10 + 1 = 11,

So 22 Ã· 2 = 11.

Question 1.

Label the array. Then, fill in the blanks to make true number sentences.

a. 18 Ã· 3 = _6_

Answer:

18 Ã· 3 = 6,

Explanation:

Labelled the array, filled the blanks to make true number sentences as

18 Ã· 3 = ( 9 Ã· 3) + (9 Ã· 3) = 3 + 3 = 6 or 18 Ã· 3 = 6.

We wrote 18 Ã· 3 as (9 + 9) Ã· 3.

b. 21 Ã· 3 = _7_

Answer:

21 Ã· 3 = 7,

Explanation:

Labelled the array, filled the blanks to make true number sentences as

21Ã· 3 = (15 Ã· 3) + (6 Ã· 3) = 5 + 2 = 7 or 21 Ã· 3 = 7.

We wrote 21 Ã· 3 as (15 + 6) Ã· 3.

c. 24 Ã· 4 = _6_

Answer:

24 Ã· 4 = 6,

Explanation:

Labelled the array, filled the blanks to make true number sentences as

24 Ã· 4 = (20Ã· 4) + (4 Ã· 4) = 5 + 1 = 6 or 24Ã· 4 = 6.

We wrote 24 Ã· 4 as (20 + 4) Ã· 4.

d. 36 Ã· 4 = _9_

Answer:

36 Ã· 4 = 9,

Explanation:

Labelled the array, filled the blanks to make

true number sentences as 36 Ã· 4 = (20Ã· 4) + (16 Ã· 4) =

5 + 4 = 9 or 36Ã· 4 = 9.

We wrote 36 Ã· 4 as (20 + 16) Ã· 4.

Question 2.

Match equal expressions.

Answer:

Matched the equal expressions as

Explanation:

Matching the equal expressions as

28 Ã· 2 = (20 Ã· 2) + (8 Ã·Â 2),

28 is written as (20 + 8) Ã· 2.

33 Ã· 3 = (30 Ã· 3) + (3 Ã· 3),

33 is written as (30 + 3) Ã· 3.

36 Ã·Â 3 = (30 Ã·Â 3) + (6 Ã·Â 3),

36 is written as (30 + 6) Ã· 3.

26 Ã· 2 = ( 20 Ã· 2) + (6 Ã· 2),

26 is written as (20 + 6) Ã· 2.

Question 3.

Alex draws the array below to find the answer to 35 Ã· 5. Explain Alexâ€™s strategy.

Answer:

Alex’s strategy is 35 Ã· 5 = (20 Ã· 5) + (15 Ã· 5) =

4 + 3 = 7, So, 35 Ã· 5 = 7,

Explanation:

To find answer for 35 Ã· 5 Alex draws an array his strategy is he divided 35 as 20 + 15 then has divided with 5,

So equation for Alex’s drawing is

35 Ã· 5 = (20 Ã· 5) + (15 Ã· 5), 4 + 3 = 7,

Therefore 35 Ã· 5 = 7.
