About this worksheet
Each worksheet has 10 problems rewriting a pair of fractions with their least common denominator.
The fraction worksheets on this site use the least common denominator constantly and never ask for it - the number line or fraction strip arrives already divided into it, as scaffolding. This standard names finding it as the skill. The student writes both fractions in full rather than naming the denominator once, because naming the multiple and writing the equivalent fraction are the two halves the standard asks for in one breath. Sheets can be customized, turned into flash cards, or assigned for online learning.
Student objectives
- Find the least common denominator of two fractions.
- Write each fraction as an equivalent fraction over it.
- Use a common multiple to compare or add fractions.
Everyday practice
- Find a denominator two fractions can share.
- Write 2/3 as twelfths.
- Say why a common denominator is needed before adding.
