What is obtained by multiplying (3.5) by (10)?
Answer and explanation
Correct answer: 35
The correct answer is 35 because \(3.5 \times 10 = 35\). When a number is multiplied by 10, its decimal point shifts one place to the right: 3.5 → 35. Option B, 3.50, is equal to 3.5, so it does not show the product. Exam tip: When multiplying by 10, 100, or 1000, shift the decimal point 1, 2, or 3 places to the right, respectively.
