### Subtracting Fractions With uncommon Denominators

Before you can subtract fractions with unlike

denominators, you need to change the fractions to

equivalent fractions (fractions with same

denominators).

Find the least common denominator (also called LCD).

This the smallest number that will divide both 9 and 3 equally ( no remainder).

**The LCM of 9 and 3 is 18**

Write an equivalent fraction with the new LCD

Subtract the numerators. The put difference over the common

denominator.

Reduce to lowest terms if needed.
