Common Mistakes to Watch For

• Reversing the order of a ratio: writing 5:3 when the problem asks for boys to girls and there are 3 boys and 5 girls in the class.
• Forgetting to multiply or divide both parts by the same number when building equivalent ratios, which breaks the relationship between the two quantities.
• Confusing part-to-part with part-to-whole: comparing red marbles to blue marbles when the question actually asks red marbles to all marbles.
