What this worksheet covers

Grade: Grade 5 (Elementary School)
Topic: Adding Fractions (Unlike Denominators)
Worksheet: Adding Proper Fractions (Unlike Denominators)

Proper fractions with unlike denominators are added, as Calculation. Expressions whose sum falls short of 1 mix with expressions that pass 1 and become mixed numbers, and pairs needing simplification stand beside pairs that do not. In Fill in the Blank the numerator for the gap is traced backward from the sum.

What Fill in the Blank shows is the sum together with the fraction that is not blank. Papers come in that fill the gap by taking the given numerator from the numerator of the sum while the denominators still differ. Put that figure back into the gap, find a common denominator and add again, and agreement with the given sum settles it.

The common denominators arranged in Properties of Fractions are used inside an addition for the first time. Adding Improper Fractions, placed next, turns the partner into a fraction larger than 1.
