Learn on PengiEureka Math, Grade 4Chapter 24: Fraction Addition and Subtraction

Lesson 3: Add and subtract more than two fractions.

Property.

Section 1

Add Fractions by Making a Whole

Property

To add multiple fractions with like denominators, find pairs whose numerators sum to the denominator.
Group these pairs to make a whole (1=nn1 = \frac{n}{n}), then add the remaining fractions to form a mixed number.
