What is 324 times 3?
972
In the equation 864 div 24 = 36, what is the divisor?
24
What is a quotient?
The answer to a division problem.
Estimate (198 times 5) by rounding 198 to 200.
1,000
There are 8 bags with 125 marbles in each bag. How many marbles are there altogether?
1,000 marbles
What is 46 times 25?
1,150
Solve 672 div 21.
32
Solve (480 div 12) using partial quotients.
40
Estimate (1,176 div 29) using compatible numbers.
About 40, because (1,200 div 30 = 40).
A school has 864 students. They are divided equally into 24 groups for an activity. How many students are in each group?
36 students
Solve 238 times 47.
11,186
Solve (1,248 div 24).
52
Solve (936 div 24) using partial quotients.
39
Estimate (3,842 div 61) using compatible numbers.
About 60, because (3,600 div 60 = 60), or approximately 63 using (3,840 div 64).
A bookstore receives 35 boxes with 48 books in each box. How many books does the bookstore receive?
1,680 books
A school orders 125 notebooks for each of 24 classrooms. How many notebooks are ordered altogether?
3,000 notebooks
A teacher has 1,575 pencils to distribute equally among 25 classrooms. How many pencils does each classroom receive?
63 pencils
Solve (1,575 div 25) using partial quotients.
63
Which is the better estimate for (2,410 div 48): 5 or 50? Explain.
50, because (2,400 div 50 = 48), which is close to the original problem.
A farmer packs 1,728 apples equally into 36 crates. How many apples go into each crate?
48 apples
A factory packs 248 crayons in each box. If it fills 36 boxes, how many crayons does it pack in all?
8,928 crayons
Solve (2,856 div 42).
68
A student solves (1,248 div 24) by subtracting (24 times 40 = 960), then subtracting (24 times 10 = 240). What is the remaining amount, and what is the final quotient?
The remainder after those subtractions is 48. Since (48 div 24 = 2), the final quotient is 52.
A student estimates (4,875 div 25) as 20. Explain why the estimate is unreasonable and give a better estimate.
It is unreasonable because 25 goes into 4,875 many more than 20 times. A better estimate is 200, because (5,000 div 25 = 200).
A school orders 24 boxes of pencils with 125 pencils in each box. The pencils are shared equally among 30 classrooms. How many pencils does each classroom receive? Show the operations needed.
First, \(24 \times 125 = 3,000\) pencils. Then, \(3,000 \div 30 = 100\). Each classroom receives 100 pencils.
