To express 2.5 as a fraction:

1. Write 2.5 as \( \frac{2.5}{1} \).
2. Multiply both the numerator and the denominator by 10 to eliminate the decimal:
   \[
   \frac{2.5 \times 10}{1 \times 10} = \frac{25}{10}.
   \]
3. Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 5:
   \[
   \frac{25 \div 5}{10 \div 5} = \frac{5}{2}.
   \]

So, \( 2.5 \) as a fraction is \( \frac{5}{2} \).
