To subtract fractions with like denominators, we subtract the numerators but keep the denominator the same. This pack of 3 mazes for adding and subtracting fractions with like denominators helps students build a solid foundation. Common (like) denominators are necessary, so change all unlike fractions to equivalent fractions with like denominators.

Always Make Sure That The Denominators Are The Same Before You Add Or Subtract.

First, you check to see if the fractions have the same denominators. If the denominators are different then a common denominator needs to be found. Given two or more fractions with unlike denominators, the lcd is the least common multiple of the denominators.

In The Case Of Like Fractions, The Denominators Will Already Be The Same, So You Can Skip Step 1 And Move To Step 2.

You can only add fractions with common denominators. To add or subtract unlike fractions, the first step is to make denominators the same so that numerators can be added just like we do for like fractions. To subtract fractions with like or the same denominator, just subtract.
