What you’ll learn

  1. When Fractions Fill UpAdd same-denominator fractions whose sum passes one whole and read the result on a number line.When same-denominator fractions add to more than one whole, the answer is bigger than 1. Adding 3/4 + 2/4 gives 5/4 — five quarters — which lands past 1 on the number line, at 1 and one more quarter.
  2. Improper Fractions and Mixed NumbersRename an improper fraction as a mixed number after adding.A fraction with a top bigger than its bottom is an improper fraction, like 5/4. It can be renamed as a mixed number — a whole and a part — because 4/4 makes one whole, so 5/4 = 1 1/4.
  3. Practice Past One WholePractice adding fractions past one whole and renaming improper answers as mixed numbers.Add the tops and keep the bottom as always: 2/3 + 2/3 = 4/3 and 4/5 + 3/5 = 7/5. Then rename the improper answer as a mixed number — 4/3 = 1 1/3 and 7/5 = 1 2/5.
