4.4H Multiplication and Division Problem Solving

Front

What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 3 multiplied by 4 (3 x 4) means adding 3 four times: 3 + 3 + 3 + 3 = 12.

Front

What is division?

Back

Division is a mathematical operation that represents the process of splitting a number into equal parts. For example, 12 divided by 4 (12 ÷ 4) means splitting 12 into 4 equal parts, which equals 3.

How do you calculate the total hours worked in a week if you work 7 hours a day for 4 days?

Back

To find the total hours worked in a week, multiply the number of hours worked per day by the number of days worked: 7 hours/day x 4 days = 28 hours.

Front

If Marcus works 28 hours a week, how many hours will he work in 32 weeks?

Back

To find the total hours worked in 32 weeks, multiply the weekly hours by the number of weeks: 28 hours/week x 32 weeks = 896 hours.

Front

What is the formula for finding the total amount when multiplying?

Back

The formula for multiplication is: Total = Number of groups x Number in each group.

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. If you know that 4 x 3 = 12, you can also say that 12 ÷ 4 = 3.

Front

What does it mean to solve a word problem in math?

Back

Solving a word problem means reading the problem carefully, identifying the mathematical operations needed, and calculating the answer based on the information given.

Front

How can you check your answer after solving a multiplication problem?

Back

You can check your answer by using division. If you multiplied to find the total, divide the total by one of the factors to see if you get the other factor.

Front

What is a key step in solving division problems?

Back

A key step in solving division problems is to determine how many equal groups can be made from the total.

Front

If you have 72 apples and want to divide them into bags of 8, how many bags can you fill?

Back

To find out how many bags you can fill, divide the total number of apples by the number of apples per bag: 72 ÷ 8 = 9 bags.
