Hi, you've already learned how to do some word problems using addition and subtraction.
Now, it's time to learn how to use multiplication and division in word problems.
Just like other word problems, these problems tell a story.
The math problem is part of our story.
In this video,
all of the word problems we use multiplication or division.
Remember, multiplication is a way of adding together groups of numbers, like a short cut.
Division tells you how many groups of a number there are.
Let's review what multiplication is.
Start with 4 x 4.
Do you remember that 4 x 4 is four fours,
or 4 + 4 + 4 + 4.
Let's put that into a word problem.
You are making a snack for 4 friends.
You each need 4 crackers.
How many crackers do you need?
You'll need 16 crackers for your snack.
Now let's try another problem.
During the field trip to the zoo the class was divided into 8 groups of 3.
How many students are in the class?
What do you need to do to figure it out?
You need to multiply.
We know that we have 8 groups, and we have 3 students in each.
You can count them up,
3,
6,
9,
12,
15,
18,
21,
24.
But, it's easier to just multiply.
Do you remember how to divide?
To divide, we are seeing how many groups we can make of a number.
That means, in this problem
we want to know how many groups of 9 we can make from 36.
Remember, you can check your work by multiplying.
4 x 9 is equal to 36.
Now, let's look at a word problem that uses division.
You have a big bag of apples.
You need to know how many pies you can make with your apples.
Your bag of apples has 24 apples, and you need 6 apples to make a pie.
How many pies can you make?
You'll need to divide 24 by 6.
You can make 4 pies.
4 x 6 is 24.
You now know how to do multiplication and division word problems.
The steps are the same for all of these multiplication and division word problems.
As you learn more about math, the word problems will get harder,
and you'll find more videos to help you learn how to work those problems.
