Understanding Word Problems in Math

The video tutorial explains how to write equations to represent information in word problems. It uses two examples: Marilyn's fish tank and Sarah's ice skating rental. For Marilyn's problem, the equation is formed by adding the number of goldfish and other fish to equal the total fish. For Sarah's problem, the equation involves multiplying the hourly rental fee by the unknown hours to equal the total cost. The tutorial emphasizes understanding known and unknown information and offers different ways to represent equations.

What is the first step in writing an equation from a word problem?

• Write down random numbers

• Identify known and unknown information

• Solve the equation immediately

• Guess the unknown value

In Marilyn's fish tank problem, what does the variable F represent?

• The number of fish tanks

• The total number of fish

• The number of goldfish

• The number of other fish

What is the known information in Marilyn's fish tank problem?

• The number of other fish

• The number of fish tanks

• The number of fish species

What is the unknown information in Marilyn's fish tank problem?

• The number of goldfish

• The total number of fish

• The number of fish tanks

• The number of other fish

What is the total number of goldfish in Marilyn's tank?

• 0

• 38

• 9

• F

How many goldfish are in Marilyn's fish tank?

• 0

• F

• 9

• 38
