Section 3: Subtracting Fractions

When both denominators are the same, subtract the numerators (the top numbers) and write the result on the top of a line; then write the denominator under that line.

Check to see if the denominators are the same. They are both 8.
Subtract the numerators:

Write the result on the top of a line and the denominator under that line:

Let's try another one:

Check to see if the denominators are the same. They are both 9.
Subtract the numerators:

Write the result on the top of a line and the denominator under that line:

Try the next one on your own:

Check to see if the denominators are the same.
Subtract the numerators.
Write the result on the top of a line and the denominator under that line.
Try one more:

Check to see if the denominators are the same.
Subtract the numerators.
Write the result on the top of a line and the denominator under that line.
