Frequently Asked Questions (FAQ)
Q1: Is 0.125 the only decimal representation of 1/8?
A: Yes, 0.125 is the exact terminating decimal. It cannot be represented as a repeating decimal because the denominator’s prime factors are only 2, which divides evenly into 10.
Q2: How do I convert any fraction to a percentage? A: Divide the numerator by the denominator to get a decimal, then multiply by 100 and add the percent sign (%). For 1/8, the steps are 1 ÷ 8 = 0.125 → 0.125 × 100 = 12.5%.
Q3: Can I use 1/8 in scientific notation?
A: Yes. In scientific notation, 0.125 is written as 1.25 × 10⁻¹. This form is useful for handling very large or very small numbers in physics and engineering Most people skip this — try not to. But it adds up..
Q4: What is the relationship between 1/8 and binary fractions?
A: In binary, 0.125 is represented as 0.001. This is because 0.125 = 1/8 = 2⁻³, and each binary place represents a power of 2 Took long enough..
Q5: How does 1/8 compare to other common fractions like 1/4 or 1/16?
A:
- 1/4 = 0.25 (25%)
- 1/8 = 0.125 (12.5%)
- 1/16 = 0.0625 (6.25%) Thus, 1/8 is exactly halfway between 1/4 and 1/16 in terms of value.
