1. The problem is to express a given number or expression as a fraction. 2. To write a number as a fraction, identify the numerator (top number) and denominator (bottom number). 3. If the number is a decimal, convert it to a fraction by writing it over a power of 10 and simplifying. 4. Simplify the fraction by dividing numerator and denominator by their greatest common divisor (GCD). 5. For example, if the number is 0.75, write it as $$\frac{75}{100}$$. 6. Simplify by dividing numerator and denominator by 25: $$\frac{\cancel{75}^{3}}{\cancel{100}^{4}} = \frac{3}{4}$$. 7. The final answer is $$\frac{3}{4}$$ as a fraction.
