Question: 165
13. 0.0515 × 100 is equivalent to
- A. 5150 ÷ 100
- B. 5.15 × 10
- C. 0.00515 × 1000
- D. 510,000 ÷ 10
Correct Answer: C
Explanation:
The correct answer is (C). 0.0515 × 100 = 5.15, and so does 0.00515 × 1000. You should be able to do this problem by moving decimal points and not by multiplying out. To divide by 10, move the decimal point one place to the left. Move it two places to the left to divide by 100, three places to divide by 1000, and so forth. To multiply by 10, 100, 1000, and so forth, move the decimal point the corresponding number of places to the right. This is an important skill to review.
