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: Mathematics: Decimals
Prompt focus: What is the product of 0.4 multiplied by 0.25?
Why the correct answer works
0.1
4 times 25 is 100, and placing three decimal places gives 0.1.
Why the tempting wrong answer fails
The tempting wrong answer usually loses because it skips the key condition, priority, or evidence in the prompt.
Plain-language takeaway
Multiply 0.4 by 0.25 by first multiplying 4 by 25 to get 100, then placing the decimal point. Since there are three total decimal places in the factors, the answer is 0.100, which equals 0.1.
Simple analogy
Think of mathematics: decimals 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
