1. Which of the following measurements is NOT equivalent?
A. 183 L = 0.183 kL
B. 24 dL = 2.4 L
C. 84 cm = 8.4 mm
D. 25 mg = 0.025 g
Answer: The correct answer is letter C. The units should be interchanged because 84 cm is not equal to 8.4 mm but rather 84 mm equal to 8.4 cm.
2. What is the conversion factor for the relationship between millimeters and centimeters?
Answer: The correct answer is letter A. One centimeter is equivalent to 10 millimeters.
3. Convert 7.54 g to kilograms.
Answer: We should know first the conversion factor between grams and kilograms. So, the conversion factor is 1 kilogram = 1,000 grams. By direct substitution:
7.54 g x (1 kg/1,000 g) = 7.54/1,000 kg = 0.00754 kg
Hence, the correct answer is letter B.
4. The metric system is based on the powers of ___.
Answer: The correct answer is letter B. Metric system is based on the powers of 10.
5. SM Mall of Asia has a land area of 42 hectares. What is the equivalent area in square meters?
