What is obtained by dividing (42.7) by (10)?
Answer and explanation
Correct answer: 4.27
The correct answer is 4.27 because dividing by 10 shifts the decimal point one place to the left: \(42.7 \div 10 = 4.27\). The distractor 0.427 would result from dividing by 100, not by 10. Exam tip: When dividing by 10, 100, or 1000, move the decimal point 1, 2, or 3 places to the left, respectively.
