Identifying the Constant of Proportionality in Tables and Graphs

What is a proportion?

• A method to multiply fractions.

• Two ratios set equal to each other.

• A mathematical operation similar to addition.

• A single ratio comparing two numbers.

How can you solve a proportion when one of the numbers is unknown?

• Finding the value that makes both sides of the equation equal.

• By guessing the missing number.

• Using subtraction on both sides of the equation.

• Multiplying both sides by the same number.

What does the variable in a proportion represent?

• A known quantity that does not change.

• The total number of ratios.

• A constant value.

• An unknown number we are trying to find.

Why is it important to do the same operation to both sides of an equation?

• To simplify the equation to a single number.

• To change the value of the variable.

• To make the equation more complex.

• To keep the equation balanced.

What is the purpose of solving equations in mathematics?

• To find the value of unknown variables.
