Real-World Problem Solving with One-Step Equations: Multiplication and Division

This video tutorial covers solving real-world problems using one-step equations involving multiplication and division. It begins with an introduction to equations and their significance in representing equal mathematical expressions. The tutorial then presents three problems: calculating the cost of candy for students, determining a dinner bill split among friends, and finding the number of books purchased. Each problem is solved step-by-step, demonstrating the use of inverse operations and verification through substitution to ensure the correctness of solutions.

What is the cost of each piece of candy if Ms. Smith bought one for each of her 22 students and the total cost was $1.10?

• $0.20

• $0.10

• $0.05

• $0.15

If three friends split a dinner bill evenly and each paid $7, what was the total bill?

• $28

• $35

• $21

• $14

What operation is used to solve the equation b divided by 3 equals 7?

• Division

• Multiplication

• Subtraction

• Addition

How many books did Deja purchase if each book cost $2 and she spent a total of $14?

• 8 books

• 7 books

• 6 books

• 5 books

In the context of solving equations, what does it mean to verify a solution?

• To guess the answer

• To check if the solution satisfies the original equation

• To change the variables

• To rewrite the equation
