What this worksheet covers

Grade: Grade 5 (Elementary School)
Topic: Adding Fractions (Unlike Denominators)
Worksheet: Adding 3 Fractions

The fractions added rise to three. Calculation, which matches all three denominators at once and then totals the numerators, is joined by Fill in the Blank, where one numerator is a gap, and by Word Problems putting three amounts together, and the answer comes out as a whole number, a proper fraction or a mixed number.

Expressions are mixed in whose numerators total exactly the denominator. A paper leaving top and bottom equal in the answer box has not finished rewriting. Where numerator and denominator stand equal, the answer is the whole number 1.

Across the five lessons of Adding Fractions (Unlike Denominators), proper fractions through mixed numbers can now be added from an expression and from a piece of writing alike. The same common-denominator procedure turns to subtracting in the next unit, Fraction Subtraction and Mixed Operations.
