Which of the following ratio is smallest?
Correct Answer: C. 10 : 36
Explanation: The correct answer is Option C: 10 : 36. To determine which ratio is the smallest, we can convert each ratio into a decimal by dividing the first number by the second: - Option A (17 : 39) is approximately 0.435. - Option B (23 : 48) is approximately 0.479. - Option C (10 : 36) is approximately 0.277. - Option D (15 : 33) is approximately 0.454.Comparing these values, 0.277 is the lowest decimal, making 10 : 36 the smallest ratio among the given choices. Alternatively, when simplified, 10 : 36 reduces to 5 : 18, which is less than one-third, while the other ratios are all closer to or greater than one-half.
