What is 0.04 x 0.03 x 0.2 in terms of percent?

24%
2.4%
0.24%
0.024%
0.0024%

Answer(s): D

Explanation:

The number we’re supposed to see in the answers is 4 x 3 x 2 = 24. It fits all answers.
The real question is the decimal of the answer; the basic rule is to add the decimals (2+2+1=5). We want the answer in percent terms so we need to take two decimals down, overall- 3.
The answer is 24/1000 (3 decimals) = 0.024%
