Convert the decimal to a fraction and reduce, if necessary.

Let’s take the decimal 0.75 as an example to convert it to a fraction. You can think of 0.75 as 75/100. If we divide both the numerator and the denominator by 25 (their greatest common divisor), we get 3/4. Voila! We have reduced the fraction.

To convert a decimal to a fraction, start by writing the decimal divided by 1 (e.g., 0.8 becomes 0.8/1). Multiply the numerator and denominator by 10 for every digit to the right of the decimal point (0.8/1 becomes 8/10). Then, reduce it to its simplest form by finding the GCD. This method lays a foundation for handling more complex decimals as well!
