This question-specific review guide is tied to the answer reasoning for a PracticeTestVault item. Use it after you answer the question so the review stays focused on what the prompt actually tested.
What this question is testing
Objective: Add and subtract fractions with unlike denominators
Prompt focus: What is the sum of 2/3 and 1/4?
Why the correct answer works
11/12
Converting to twelfths gives 8/12 plus 3/12, which sums to 11/12.
Why the tempting wrong answer fails
This would result from a subtraction error rather than addition.
Plain-language takeaway
To add fractions, find a common denominator. The least common denominator of 3 and 4 is 12, giving 8/12 plus 3/12, which equals 11/12.
Simple analogy
Think of add and subtract fractions with unlike denominators like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
How to review it before a retake
