Difficulty: EasyBasic Ratios

During a ship repair project, a naval shipyard assigns 24 welders and 8 pipefitters to complete the structural work. What is the ratio of welders to pipefitters on this project, expressed in its simplest form?

  1. 3:1Answer
  2. B
    1:3
  3. C
    3:4
  4. D
    1:4

Answer

3:1
The correct answer accurately extracts the given quantities (24 welders, 8 pipefitters), sets them up in the requested sequence (24 to 8), and successfully reduces the numbers to their simplest terms by dividing both by 8, yielding 3:1.

Step-by-Step Solution

1
Identify the two quantities that need to be compared based on the question.
Welders = 24, Pipefitters = 8
The question asks for the specific ratio of welders to pipefitters.
2
Set up the initial ratio in the exact order requested by the problem.
24:8
The order of terms in a ratio matters; it must strictly match 'welders to pipefitters'.
3
Simplify the ratio by dividing both numbers by their greatest common divisor (GCD).
The GCD of 24 and 8 is 8. Therefore, (24 ÷ 8) : (8 ÷ 8) = 3:1
Ratios are conventionally expressed in their lowest possible integer terms.
