Adding and Subtracting Fractions with Common Denominators

Identify and write the fractions. Count the sections of the smaller fraction Mark an X on each section of the larger fraction to show how many you will subtract. Count the shaded sections that you have left—this is the numerator of the difference.

If you fill in this shape, you have 5 out of 5 or ONE and one fifth left in the other fraction.

If you fill in this shape, you have 4 out of 4 or ONE and two fourths left in the other fraction.
