Question 3 of 5
Express the ratio of 6:7 as a percentage.
Correct Answer: A
Rationale:
To express the ratio 6:7 as a percentage, we first need to find the total parts in the ratio, which is 6 + 7 = 13.
To convert this ratio to a percentage, divide the part you want to find the percentage for by the total parts, then multiply by 100. In this case, to find the percentage for 6 in the ratio 6:7, the calculation would be (6/13) * 100 = 46.15%.
Therefore, the correct answer is A, 67%.
Choices B, C, and D are incorrect percentages as they do not result from the correct calculation for the given ratio.
