Identify the divisor.
What is 4?
The divisor is the number of groups we are dividing the dividend (in this case 20) by.
Solve:
360 ÷ 9 =
40
We know the term "inverse operation" is just fancy for doing the opposite operation in Math!
Using the inverse, find the missing number in this equation: 3 x ___ = 12
The inverse to Multiplication is Division
12 ÷ 3 = 4
What is the answer to a division problem?
The quotient is the answer to a division problem. Here, 20 divided by 4 = 5 and 5 is the answer.
Solve:
480 ÷ 60 =
8
Use compatible numbers, which is the best estimate for 564 ÷ 73
Compatible numbers are those that work easily together, whether you're dividing or multiplying, adding or subtracting. Numbers we can work with mentally.
564 could drop to 560 and 73 could drop to 70 since I know 56 is a multiple of 7!
560 ÷ 70 = 56 ÷ 7 (zeros cancel out!) = 8
What is the dividend?
20
The dividend (20 here) is the number that is being divided into groups.
Solve:
7,200 ÷ 8 =
900
Use compatible numbers to estimate 3,524÷49.
Compatible numbers are those that work easily together, whether you're dividing or multiplying, adding or subtracting. Numbers we can work with mentally.
3,424 could change to 3,500 and 49 could round up to 50 since I know 35 is a multiple of 5!
3500 ÷ 50 = 350 ÷ 5 (1 zero cancel out, one remains in your answer!) = 70
Define remainder.
The remainder is anything that is leftover in the problem once solved.
Solve:
24,000 ÷ 60 =
400
A parking lot has 270 parking spaces. Each row has 9 parking spaces. How many rows are in this parking lot?
270 ÷ 9
9 goes into 270 evenly 30 times
30 rows
Define inverse.
The inverse operation simply means the opposite.
Which has a quotient of 50? There can be more than 1 answer.
A. 100 ÷ 4 =
B. 1000 ÷ 40 =
C. 1000 ÷ 20 =
D. 100 ÷ 2 =
Tricked you! There are TWO correct answers!

For Mother's Day, Rob makes a scrapbook for his mom. There are 40 pictures that he needs to put in the scrapbook. He puts 4 pictures on each page. How many pages does the scrapbook have?
If only 4 photos fit on a page, you'll need to divide 40 by 4.
40 ÷ 4 = 10
