Basics on the topic Solving Equations with Multiplication and Division—Let's Practise!
Understanding Solving Equations with Multiplication and Division – Introduction
We're diving into the world of solving equations with multiplication and division. These skills are essential for solving real-world problems. Get ready because today, we're going to practise this together!
What Is Solving Equations with Multiplication and Division?
Solving equations with multiplication and division involves writing an equation based on a word problem and then solving it step-by-step. This method helps us understand how to represent real-life situations mathematically.
Here are the steps to tackle solving equations with multiplication and division:
Step # | Action |
---|---|
1 | Read the word problem carefully. |
2 | Identify the numbers and what they represent. |
3 | Write an equation using multiplication or division. |
4 | Solve the equation. |
5 | Check your answer to ensure it makes sense with the problem. |
Let's practise understanding this method with a few examples.
Solving Equations with Multiplication and Division – Examples
Example 1:
Problem: Kiara's class is having a pizza party. There are eight pizzas and each pizza has six slices. How many slices are there in all?
Steps to Solve the Problem:
Step # | Action | Description |
---|---|---|
1 | Read the problem carefully. | Kiara's class has eight pizzas. |
2 | Identify the numbers and their meaning. | Each pizza has six slices. |
3 | Write the equation. | $8 × 6 = P$ P represents slices |
4 | Solve the equation. | $8 × 6 = 48$ |
5 | Check the answer. | There are 48 slices in all. |
Solution: The total number of slices is 48.
Example 2:
Problem: Javier invited thirty-five friends to his birthday party and each table can fit seven seats. How many tables does Javier need?
Steps to Solve the Problem:
Step # | Action | Description |
---|---|---|
1 | Read the problem carefully. | Javier has thirty-five friends. |
2 | Identify the numbers and their meaning. | Each table fits seven seats. |
3 | Write the equation. | $35 ÷ 7 = T$ T represents tables |
4 | Solve the equation. | $35 ÷ 7 = 5$ |
5 | Check the answer. | Javier needs 5 tables. |
Solution: Javier needs 5 tables.

Determine if a problem is multiplication or division.
HintsSplitting up a total equally is dividing. Adding the same amount multiple times is multiplication.
The word each is often a signal word for division word problems.
Making or producing something is often a signal word for multiplication word problems.
Solution- The equation for word problem 1 should read 12 ÷ 3. This uses division.
- The equation for word problem 2 should read 40 ÷ 10. This uses division.
- The equation for word problem 3 should read 5 x 5. This uses multiplication.
- The equation for word problem 4 should read 5 x 4. This uses multiplication.
-
Find the equation and solution.
HintsSplitting up a total equally is dividing. Adding the same amount multiple times is multiplication.
The words double, triple, quadruple or times are often signal words for multiplication word problems.
Double means to multiply by 2 or add a number two times.
Solution2 x 5 = 10
- Zuri scored 5 goals in the first game. In the second game she doubled her score.
- When you double something, it means to multiply by 2.
- The equation is 2 x 5 = 10. Zuri scored 10 goals in her second match.

Find the equation and solution.
HintsStart by finding the total, then find the number you need to divide by.
There are 35 guests in total and you're dividing the guests into tables that seat 5.
The below image illustrates 35 people sitting 5 people to one table.
SolutionThe image above illustrates the word problem.
Charlie will need 7 tables. If there are 35 guests in total and each table can sit 5 people, then the equation and solution is 35 ÷ 5 = 7.
