1. Lana makes clothes for her online store. She makes 19 shirts from a large roll of fabric. Each roll has 610 inches of fabric. How many inches of fabric from the roll does Lana use for each shirt?

A. Write a division problem to represent the situation and estimate the answer.
_______________
B. Divide the tens. Share the tens equally among the 19 groups.

How many tens are in each group? ____
Multiply the result by the divisor and subtract it from the dividend. Record. 61 tens – 57 tens = ___ tens
C. Divide the ones. Regroup 4 tens as 40 ones. Share the ones equally among the 19 groups. How many ones are in each group? ____
Multiply the result by the divisor and subtract. Record.
40 ones – 38 ones = ___ ones
The division problem is 610 ÷ 19, the estimated answer is 32 remainder 2,
It is reasonable.

Explanation:
Given Lana makes clothes for her online store.
She makes 19 shirts from a large roll of fabric.
Each roll has 610 inches of fabric.
The division problem to represent the situation and estimated the answer as 610 ÷ 19
19)610(32
57
40
38
2
the estimated answer is 32 remainder 2,
It is reasonable.

Turn and Talk What does the remainder tell you about the amount of fabric Lana needs to make another shirt?
The remainder tells us Lana requires
more amount of 30 inches of fabric to make another shirt,

2. Lana’s shirts are a hit! Fab Fashion is a company with stores across the country as shown. The company orders 1,200 of her shirts. If each store receives the same number of shirts in the first shipment, how many shirts will each store receive?

A. Use compatible numbers to estimate 1,200 ÷ 38.
______________________
B. Divide the tens. Multiply the result by the divisor and subtract it from the dividend. Record.

C. Divide the ones. Multiply the result by the divisor and subtract it from the dividend. Record.
D. How many shirts will each store have, and how many will be left over?
Each store will have 31 shirts and
22 shirts will be left over,

Explanation:
Given Lana’s shirts are a hit! Fab Fashion is a company with stores across the country as shown.
The company orders 1,200 of her shirts.
If each store receives the same number of shirts in the first shipment, shirts will each store receive are
38)1,200(31
114
60
38
22
31 shirts.
therefore each store will have 31 shirts and 22 shirts will be left over,

Turn and Talk Suppose you let a represent the dividend, b the divisor, q the whole-number quotient, and r the remainder in a division problem. What equation could you write to show how these values are related? What does the equation model in this situation?
Equation is Dividend = b X q + r,

Explanation:
Let a represent the dividend, b the divisor,
q the whole-number quotient, and
r the remainder in a division problem.
Equation for these values are related as
Dividend = Divisor x Quotient + Remainder,
Equation is Dividend = b X q + r.

Question 1.
A museum director wants to display 609 objects in 21 rooms so that each room has the same number of objects. Write a division problem to represent the situation. Estimate, and then find, the number of objects to be displayed in each room. Show your division.
The number of objects to be displayed in each room are 29,

Explanation:
Given a museum director wants to display 609 objects in 21 rooms so that each room has the same number of objects.

29 objects.

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?
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
128 ÷ 11 =
11) 128(11
11

11
7
11 chairs and many chairs are left over 7 chairs.

Question 3.
960 ÷ 24
40,

Explanation:
Given to divide 960 ÷ 24
24) 960(40
960
0
So 960 ÷ 24 = 40.

Question 4.
3,279 ÷ 82
39 remainder 81,

Explanation:
Given to divide 3,279 ÷ 82
82) 3279(39
246
819
738
81
so 3,279 ÷ 82 = 39 remainder 81.

Question 5.

17 remainder 4,

Explanation:
Given to divide 769 ÷ 45,
45)769(17
45
319

So 769 ÷ 45 = 17 remainder 4.

Question 6.

55,

Explanation:
Given to divide 2,145 ÷ 39 ,
39 )2145(55
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 the phone is filled with only songs or only podcasts, how many megabytes would be left on the phone?

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.
If only songs 4515 ÷ 12
12)4515(376

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 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?

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 has 80 buttons only so by dividing it by each dress requires 11 buttons we get whole dresses
she can make are 7 dresses as 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 leftover.
