Answer
Correct Answer: a, d, b, c
Explanation
Introduction / Context:Metric prefixes denote powers of ten. We arrange them from the smallest factor to the largest.
Given Data / Assumptions:
- centi = 10^-2.
- deci = 10^-1.
- deca = 10^1.
- kilo = 10^3.
Concept / Approach:Order by exponent value: negative exponents (fractions of base) come before positive exponents (multiples of base).
Step-by-Step Solution:
Smallest: centi (a) = 10^-2.Next: deci (d) = 10^-1.Then: deca (b) = 10^1.Largest: kilo (c) = 10^3.Verification / Alternative check:Compare numerically: 0.01 < 0.1 < 10 < 1000 — consistent.
Why Other Options Are Wrong:
- Any order placing kilo before deca or negative exponents after positives is inconsistent with magnitudes.
Common Pitfalls:Mixing “deci” and “deca” due to similar spelling; note opposite sides of the base unit.
Final Answer:a, d, b, c
