To express the result in decimal form, you divide by 100.
Therefore, the result is 1.
Choice A (0.01) is incorrect as it represents 1/100, not the result of 25 4.
Choice B (0.1) is incorrect as it represents 1/10.
Choice D (10) is incorrect as it is the result before converting it to decimal form.

Rationale:
To convert a fraction to a percentage, you multiply the fraction by 100.
To express 4/5 as a percent, you perform the calculation 4/5 * 100 = 80%.
Therefore, the correct answer is D, 80%.

Choices A, B, and C are incorrect as they do not represent the correct conversion of 4/5 to 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.

Correct Answer: C
