11. 1 is 3 percent of what number?

Answer: D

Explanation:

1 is 3 percent of 33 1/3.

To find the number of which 1 is 3 percent, we set up the equation \(0.03 \times x = 1\). Solving for \(x\) gives us \(x = \frac{1}{0.03} = 33.\overline{3}\), confirming that 1 is indeed 3 percent of 33 1/3.

A) 13

Option A is incorrect because if we take 3 percent of 13, we get \(0.03 \times 13 = 0.39\), which is not equal to 1. Therefore, 13 cannot be the number we are looking for.

B) 3

Option B is also incorrect. Calculating 3 percent of 3 results in \(0.03 \times 3 = 0.09\), which does not equal 1. Thus, 3 cannot be the correct number.

C) 30

Option C fails as well, since 3 percent of 30 equals \(0.03 \times 30 = 0.9\), which is less than 1. Consequently, 30 is not the correct answer.

D) 33 1/3

Option D is correct because when we compute 3 percent of \(33 \frac{1}{3}\), or \(33.33\), we find \(0.03 \times 33.33 = 1\). This confirms that 1 is indeed 3 percent of this number.

Conclusion

Option D is definitively the correct answer as it accurately represents the number from which 1 is derived as 3 percent. All other options fail to meet the criteria since their calculations do not yield the required result of 1 when 3 percent is applied.
