Find the value of (0.02^3 + 0.002^3) / (0.04^3 + 0.002... ). Compute (0.02^3 + 0.002^3) divided by (0.04^3 + 0.004^3).

1. 1/2
2. 1/4
3. 1/8
4. 1/16

Correct answer: 1/8

Solution

Numerator = 0.02^3(1 + 0.1^3) and denominator = 0.04^3(1 + 0.1^3). The (1 + 0.1^3) terms cancel, leaving (0.02/0.04)^3 = (1/2)^3 = 1/8.
