Here are the steps on how to subtract fractions:

1. Make sure the fractions have the same denominator (bottom number):

- If the fractions already have the same denominator, you can skip this step.
- If the denominators are different, you need to find the least common multiple (LCM) of the two denominators. This is the smallest number that is a multiple of both denominators.
- Once you have the LCM, multiply the numerator and denominator of each fraction by the factors needed to get the LCM in the denominator.
