## Practice Solving Proportions

Instructions:

Answer 7/10 questions correctly to pass.

Solve each proportion problem.

Fractions must be simplified.

Negative fractions can be written as -a/b or a/-b.

Problem:

Correct! Not Correct! Solving Proportion Equations:

1. Use the cross products to set up a linear equation in one variable.
• Multiply the denominator of the left fraction by the numerator of the right fraction.
• Multiply the denominator of the right fraction by the numerator of the left fraction.
2. Solve the linear equation.
• Move all variable terms to the left side.
• Move all numbers to the right side.
• Isolate the variable.
• We obtain our answer as: x = "a number"

Solving Proportion Word Problems:

1. Set up a proportion equation based on the information in the problem
• The numerators must represent the same quantities
• The denominators must represent the same quantities
2. Solve the proportion equation and report the answer
