Compare three quantities in different forms: Which is greatest among 33 1/3%, 4/15, and 0.35?

Difficulty: Easy

Correct Answer: 0.35

Explanation:


Introduction / Context:
Comparing values presented as a percent, a fraction, and a decimal is a common skill. The easiest route is to convert all three to the same form (usually decimals) and then compare.


Given Data / Assumptions:

  • 33 1/3% = 1/3 = approximately 0.3333…
  • 4/15 ≈ 0.2666…
  • 0.35 is already a decimal.


Concept / Approach:
Convert each to decimal (or to percent) and compare numerically. Ensure adequate precision to avoid ties caused by rounding.


Step-by-Step Solution:

33 1/3% = 33.333…% = 0.3333…4/15 = 0.2666…0.35 = 0.3500…Hence, 0.35 > 0.3333… > 0.2666…


Verification / Alternative check:
As percents: 33 1/3% ≈ 33.33%; 4/15 ≈ 26.67%; 0.35 = 35%. The largest is 35%.


Why Other Options Are Wrong:

  • 33 1/3% is smaller than 0.35.
  • 4/15 is the smallest of the three.
  • “Cannot be compared” is incorrect; precise decimal equivalents make comparison straightforward.


Common Pitfalls:
Misconverting the mixed percent or the fraction. Write at least three to four decimal places for a clean comparison.


Final Answer:
0.35
