Simplifying fractions worksheets
A fraction in lowest terms is the tidiest way to write an amount: six eighths and three quarters are the same size, but three quarters says it with the smallest numbers. These free printable worksheets give a fraction that can be reduced and ask a child to write it in lowest terms.

The answer key prints on a separate page.
What's on this sheet
The clean method is to divide the top and bottom by their greatest common factor. Six and eight share a factor of two, so six eighths becomes three quarters in a single step; had they shared a four, one division would still have finished it. Dividing by the GCF is fastest, but dividing by any common factor and repeating gets to the same place — it just takes more steps.
Why this sheet works
Every fraction on the page is built to reduce, so there is always real work to do, and each answer stays a proper fraction with a numerator below its denominator — nothing that secretly equals a whole, and no mixed numbers. Knowing when to stop is half the skill: a fraction is finished when the only factor its top and bottom still share is one.
How this one works
