In adding and subtracting fractions with unlike denominators, you have to get a least common denominator which is exactly like the least common multiple it just so happens to be in the denominator.

Have you ever tried to add or subtract fractions that have different denominators? It’s tricky, right? Join Ms. Susanna Post in this lesson to learn how to solve these types of challenging problems!

Students will find common denominators to help add fractions with unlike denominators. Students will join Ms. MacDonald to find common denominators to help add fractions with unlike denominators.

Fractions can be added in different ways: When the denominators are the same, add the numerators. Sometimes the final answer can be simplified. close simplify (a fraction)To reduce a fraction to its ...

Each fraction has the same denominator. Use the numerators to order the fractions. The smaller the numerator, the smaller the fraction. The numerators are all the same. Use the denominators to order ...
