To solve the equation \( 27^{\frac{3}{4} - 1} = 26 \), we first simplify the left side.

  1. Start with the exponent: \( \frac{3}{4} - 1 = \frac{3}{4} - \frac{4}{4} = \frac{3 - 4}{4} = \frac{-1}{4} \).

  2. Rewrite the equation: \[ 27^{\frac{-1}{4}} = 26 \]

  3. Rewrite \( 27 \) as \( 3^3 \): \[ (3^3)^{-\frac{1}{4}} = 26 \] \[ 3^{-\frac{3}{4}} = 26 \]

  4. Take the reciprocal: \[ \frac{1}{3^{\frac{3}{4}}} = 26 \]

  5. Inverting gives: \[ 3^{\frac{3}{4}} = \frac{1}{26} \]

Now, we need to analyze the options given:

  1. \( \frac{25}{27} \)

  2. \( 1 \)

  3. \( 0 \)

  4. \( 3 \)

Since \( 3^{\frac{3}{4}} \) is not 1, 0, or 3, we'll calculate the approximate value of \( 3^{\frac{3}{4}} \).

Taking \( 3^{0.75} \) directly: \[ 3^{0.75} \approx 2.279 \]

Thus, it's not equal to any of the provided options, but since none of these directly solve for \( x \) in the form given, we might need to consider:

  • Rearranging back or reevaluating if it's an arbitrary check based on number sense — yet \( 26 \) is significantly larger than any of these choices besides the \( 1 \).

However, resolving the exact interpretation and calculation seems neglected here under exponent rules, nevertheless with a numerical evaluation \( 3^{\frac{3}{4}} \) appears closer akin to approximating if ratio-led insight into each divisor indicative of fraction checks.

Since the problem's restrictions suggest a calculative output or raw distance from integers; the nearest viable option gauged around an equal point shaping might thus land at:

Thus, the correct answer could be \( 1 \) if seeking measurable proximity within groupings, but needs review if those foundational checks exist beyond mere ratio-based notation interchangeably.

Conclusion:

Among the provided options without numerical precision guiding directly to ratio, choose \( 1 \).
