To convert 0.75 to a fraction, we can start by expressing it as \( \frac{75}{100} \).
Next, we simplify \( \frac{75}{100} \) by finding the greatest common divisor (GCD) of 75 and 100. The GCD is 25.
Now we can simplify it:
\[ \frac{75 \div 25}{100 \div 25} = \frac{3}{4} \]
Thus, 0.75 converted to a fraction in simplest form is \( \frac{3}{4} \).
