Basic percent of a whole: 50 kg is what percent of 250 kg?

Introduction / Context:This is a direct percent-of-whole computation: part divided by whole, then converted to a percentage. Units cancel as both quantities are in kilograms.

Given Data / Assumptions:

• Part = 50 kg.
• Whole = 250 kg.

Concept / Approach:Percentage = (Part / Whole) * 100. Ensure the base (whole) is the 250 kg amount, not the 50 kg amount.

Step-by-Step Solution:(50 / 250) * 100 = 0.2 * 100 = 20%

Verification / Alternative check:Since 50 is one-fifth of 250, the percent is 20% (because 1/5 = 20%).

Why Other Options Are Wrong:15%, 18%, 25%, 26% do not reflect the 1:5 ratio.

Common Pitfalls:Accidentally dividing 250 by 50 (giving 500%) or forgetting to multiply by 100.

Final Answer:20%
