The question in the image asks how to express the repeating decimal \( 1.27\overline{7} \) (where the 7 repeats) as a fraction.

### Steps to Convert \( 1.27\overline{7} \) to a Fraction:
1. Let \( x = 1.27\overline{7} \), meaning \( x = 1.277777\ldots \) (where the 7 repeats indefinitely).
2. Multiply both sides of the equation by 10 to shift the decimal point past the repeating part:
   \[
   10x = 12.77\overline{7}
   \]
3. Now subtract the original \( x = 1.27\overline{7} \) from this new equation:
   \[
   10x - x = 12.77\overline{7} - 1.27\overline{7}
   \]
   This simplifies to:
   \[
   9x = 11.5
   \]
4. Solve for \( x \):
   \[
   x = \frac{11.5}{9} = \frac{115}{90}
   \]
5. Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD = 5):
   \[
   x = \frac{115 \div 5}{90 \div 5} = \frac{23}{18}
   \]

Thus, \( 1.27\overline{7} = \frac{23}{18} \).

### Comparing the options:
From the available options, none exactly match \( \frac{23}{18} \), but the fraction \( \frac{5}{18} \) is present, which could be a simpler version of the answer presented. The correct answer, however, is likely a typo or rounding mistake. You should verify this with the platform.
