Sam's Weight (Represent word problems involving multiplicative comparison using a symbol for the unknown where the numbe

The video tutorial explains how to compare the weights of Sam and his brother Rick using a multiplicative comparison. It introduces the problem of determining how many times Sam is heavier than Rick by setting up an equation with an unknown multiplier. The tutorial demonstrates solving the equation 8 * H = 40 to find that Sam is 5 times heavier than Rick. It also shows how division can be used to find the same result. The lesson concludes by summarizing the method of using equations with symbols to solve multiplicative comparison problems.

What is the initial question posed about Sam and Rick's weights?

• How old are Sam and Rick?

• What is the total weight of Sam and Rick?

• How many times is Sam heavier than Rick?

• How much does Sam weigh?

What equation is used to find out how many times Sam is heavier than Rick?

• 8 + H = 40

• 8 - H = 40

• 8 * H = 40

• 8 / H = 40

What symbol is used to represent the unknown multiplier in the equation?

• Number 5

• Letter H

• Rectangle

• Circle

How can we verify that Sam is 5 times heavier than Rick?

• By adding 8 to 5

• By multiplying 8 by 8

• By dividing 40 by 8

• By subtracting 8 from 40

What mathematical operation can be used to find the unknown multiplier besides multiplication?
