**Find the difference.**

Question 1.

Answer:

Explanation:

Given to find the difference of

54

-35

19

as 4 is less than 5 we borrow 1 from tens and subtract 14 – 5 we get 9 at ones place, next we subtract the subtrahend tens digit from new minuend tens digit as 4 – 3 = 1,

so the difference is 54 – 35 = 19.

Question 2.

Answer:

Explanation:

Given to find the difference of

72

-48

24

as 2 is less than 8 we borrow 1 from tens and subtract 12 – 8 we get 4 at ones place, next we subtract the subtrahend tens digit from new minuend tens digit as 6 – 4 = 2,

so the difference is 72 – 48 = 24.

Question 3.

Answer:

Explanation:

Given to find the difference of

85

-67

18

as 5 is less than 7 we borrow 1 from tens and subtract 15 – 7 we get 8 at ones place, next we subtract the subtrahend tens digit from new minuend tens digit as 7 – 6 = 1,

so the difference is 85 – 67 = 18.

**Relate Multiplication and Division**

**Write the related facts for each set.**

Question 4.

4, 6, 24

____ ÷ ___ = ___

____ × ____ = ___

____ ÷ ___ = ___

____ × ____ = ___

Answer:

24 ÷ 6 = 4,

6 X 4 = 24,

24 ÷ 4 = 6,

4 X 6 = 24,

Explanation:

Given numbers are 4,6, 24 the related facts are if we divide 24 by 6 we will get 4 so 24 ÷ 6 = 4,

if we multiply 6 by 4 we will get 24, 6 X 4 = 24,

if we divide 24 by 4 we will get 6, 24 ÷ 4 = 6,

if we multiply 4 by 6 we will get 24, 4 X 6 = 24.

Question 5.

7, 9, 63

____ ÷ ___ = ___

____ × ____ = ___

____ ÷ ___ = ___

____ × ____ = ___

Answer:

63 ÷ 9 = 7,

7 X 9 = 63,

63 ÷ 7 = 9,

9 X 7 = 63,

Explanation:

Given numbers are 7,9,63 the related facts are

if we divide 63 by 9 we will get 7 so 63 ÷ 9 = 7,

if we multiply 7 by 9 we will get 24, 7 X 9 = 63,

if we divide 63 by 7 we will get 9, 63 ÷ 7 = 9,

if we multiply 9 by 7 we will get 63, 9 X 7 = 63.

Question 6.

5, 8, 40

____ ÷ ___ = ___

____ × ____ = ___

____ ÷ ___ = ___

____ × ____ = ___

Answer:

40 ÷ 5 = 8,

5 X 8 = 40,

40 ÷ 8 = 5,

8 X 5 = 40,

Explanation:

Given numbers are 5,8,40 the related facts are

if we divide 40 by 5 we will get 8 so 40 ÷ 5 = 8,

if we multiply 5 by 8 we will get 40, 5 X 8 = 40,

if we divide 40 by 8 we will get 5, 40 ÷ 8 = 5,

if we multiply 8 by 5 we will get 40, 8 X 5 = 40.

Question 2.

A conference coordinator has 128 chairs to arrange in 11 rows. If each row has the same number of chairs, how many chairs are in each row? How many chairs are left over?

Answer:

In each row there are 11 chairs and 7 chairs are left over,

Explanation:

Given a conference coordinator has 128 chairs to arrange in 11 rows.

If each row has the same number of chairs,

Number of chairs are in each row are

55,

Explanation:

Given to divide 2,145 ÷ 39 ,

39 )2145(55

195

195

0,

So 2,145 ÷ 39 = 55.

Question 7.

**Use Repeated Reasoning** A cell phone has 4,515 megabytes of storage space available. Each downloaded song is 12 megabytes, and each downloaded podcast is 84 megabytes.

- If only songs or only podcasts are downloaded, how many more songs than podcasts can be downloaded? Explain your thinking.

______________________

______________________ - If the phone is filled with only songs or only podcasts, how many megabytes would be left on the phone?

______________________

_____________________

Answer:

More songs than podcasts can be downloaded are

323 songs,

If the phone is filled with only songs

megabytes would be left on the phone are 3 mega bytes,

If the phone is filled with only podcasts,

megabytes would be left on the phone is 63 mega bytes.

Explanation:

Given A cell phone has 4,515 megabytes of storage space available.

Each downloaded song is 12 megabytes and

each downloaded podcast is 84 megabytes.

If only songs 4515 ÷ 12

12)4515(376

If only podcast 4515 ÷ 84

84)4515(53

420

315

252

63

If only songs or only podcasts are downloaded, more songs than podcasts can be downloaded are only songs we have 376 and only podcasts we have 53

so 376- 53 = 323 more songs.

If the phone is filled with only songs megabytes would be left on the phone are 3 mega bytes,

If the phone is filled with only podcasts, megabytes would be left on the phone is 63 mega bytes.

Question 13.

**Use Repeated Reasoning** Krithika makes green dresses with buttons. Each dress requires 11 buttons and 72 inches of green fabric.

- Krithika has a box of 80 buttons and a roll of 500 inches of fabric. How many whole dresses can she make using these items? Explain how you found your answer.
- How many buttons and inches of fabric will be left over after making this number of dresses? How do you know?

Answer:

6 whole dresses,

14 buttons and 68 inches of fabric will be left

Explanation:

Given Krithika makes green dresses with buttons.

Each dress requires 11 buttons and 72 inches of green fabric.

Krithika has a box of 80 buttons and a roll of 500 inches of fabric.

Whole dresses can she make using these items are

11)80(7

77

3

as Krithika have 80 buttons only so by dividing it by each dress requires 11 buttons we get whole dresses.

she can make are 7 dresses for 1 dress she requires 72 inches of green fabric for 7 dresses she requires

72 X 7 = 504 but we have the fabric of only 500 inches,

So Krithika will make only 6 dresses only,

Buttons required are 6 X 11 = 66 buttons and fabric is 72 X 6 = 432 inches, Now buttons and inches of fabric will be leftover after making this number of dresses are 80 buttons – 66 buttons = 14 buttons,

500 inches – 432 inches = 68 inches, by calculating as above given information, we came to know about left over.
