What is 0.01 x 5 x 0.03 in terms of percent?
A. 15%
B. 1.5%
C. 0.15%
D. 0.015%
E. 0.0015%
Correct Answer: C
Explanation/Reference:
Explanation:
Since 0.01 and 0.03 each have 2 decimal places, their product must have 4 (2 + 2) decimal places. Because 1 x 3 x 5 is 15, you need to add 2 zeros to get the correct number of decimal places, so the product of 0.01, 5 and 0.03 is 0.0015. To change a decimal to a percentage you multiply by 100 and move the decimal point 2 places to the right, so 0.0015 is 0.15%. The correct answer is C.
