Determine the lowest common denominator.
Multiply the numerator and denominator of each fraction by a number that will result in the denominator becoming the LCD. The purpose for multiplying both the numerator and denominator is that any number divided by itself = 1, and when you multiply something by 1, you don't change it.
When subtracting two fractions with the same denominators, the first numerator minus the second numerator equals the numerator of the result, and the result has the same denominator (the LCD).

There are three types of fractions that are used in mathematics. The three types of fractions are, mixed fractions, proper fractions, and improper fractions.
Regular fractions are the fractions with a numerator that is less than the denominator and irregular fractions are fractions with a denominator less than the numerator.
Like fractions have the same denominator, unlike fractions don't.
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

There is no such thing as THE two fractions. There are infinitely many fractions.
