Adding and Subtracting Fractions
It is easiest to work with proper or improper fractions when adding or subtracting fractions. If the fraction is mixed, simply convert it to an improper fraction before you start. There are three simple steps to adding or subtracting fractions.
- Step 1: Make sure the denominators are the same (lowest common denominator).
- Step 2: Add or subtract the numerators and put the answers over the same deonominator
- Step 3: Simplify the fraction (if needed).
Example: \(\frac{3}{4}-\frac{1}{4}\)
Solution:
Since both deonominators are the same, go to step 2:
\(\frac{3}{4}-\frac{1}{4}=\frac{3-1}{4}=\frac{2}{4}\)
Now, simplify the fraction:
\(\frac{2}{4}=\frac{1}{2}\)
