1. The problem is to convert a decimal number to a fraction. 2. The general formula to convert a decimal to a fraction is to write the decimal number as the numerator and the place value of the last digit as the denominator. 3. For example, if the decimal is $0.75$, it can be written as $\frac{75}{100}$ because the last digit is in the hundredths place. 4. Simplify the fraction by dividing numerator and denominator by their greatest common divisor (GCD). 5. For $0.75$, the GCD of 75 and 100 is 25, so: $$\frac{75}{100} = \frac{\cancel{75}^3}{\cancel{100}^4} = \frac{3}{4}$$ 6. Therefore, $0.75$ as a fraction is $\frac{3}{4}$. This method applies to any decimal number.
