Percentage Calculation: Comparing Identical Values

The question asks to determine what percentage a specific value is of itself. Let's break this down:

  • Let the unknown number be represented by '\(N\)'.
  • Calculate the first value: 5% of the number. This can be written as \(0.05 \times N\).
  • The second value is also 5% of the same number, which is \(0.05 \times N\).
  • We need to find what percentage the first value (\(0.05 \times N\)) is of the second value (\(0.05 \times N\)).

Determining the Percentage

To find what percentage value 'A' is of value 'B', we use the formula:

\( \text{Percentage} = \frac{A}{B} \times 100\% \)

In this case:

  • \(A = 5\% \times N = 0.05N\)
  • \(B = 5\% \times N = 0.05N\)

Substituting these into the formula:

\( \text{Percentage} = \frac{0.05N}{0.05N} \times 100\% \)

Assuming the number '\(N\)' is not zero, the value \(0.05N\) is non-zero, and we can simplify the fraction:

\( \text{Percentage} = 1 \times 100\% \) \( \text{Percentage} = 100\% \)

Therefore, 5% of a number is 100% of 5% of the same number.
