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

The video tutorial covers solving real-world problems using one-step equations involving multiplication and division. It begins with an introduction to equations, emphasizing the need for balance on both sides. Three problems are presented: calculating the cost of candy for students, determining a dinner bill split among friends, and finding the number of books purchased at a sale. Each problem is solved by forming an equation, performing operations to isolate the variable, and verifying the solution through substitution.

What is an equation?

• A mathematical operation

• A variable

• A number

• A statement that two expressions are equal

How do you solve the equation 22c = $1.10?

• Multiply both sides by 22

• Divide both sides by 22

• Add 22 to both sides

• Subtract 22 from both sides

What is the cost of each piece of candy if 22 pieces cost $1.10?

• $0.20

• $0.10

• $0.05

• $0.15

If three friends split a bill evenly and each pays $7, what is the total bill?

• $14

• $35

• $21

• $28

How do you solve the equation b/3 = 7?

• Add 3 to both sides

• Subtract 3 from both sides

• Multiply both sides by 3

• Divide both sides by 3

If each book costs $2 and the total spent is $14, how many books were purchased?

• 7 books

• 8 books

• 6 books

• 5 books

How do you solve the equation 2b = 14?

• Multiply both sides by 2

• Divide both sides by 2

• Add 2 to both sides

• Subtract 2 from both sides
