Exact rationals beat early decimals when you still need to cancel factors
How Fraction Worksheets Keep Results in Lowest Terms
A good fraction worksheet does not pretend to be a symbolic CAS. It does one job well: take two integer fractions, apply a single operation, and refuse to leave an unsimplified answer. That discipline matches what teachers mark on paper.
Simplify Inputs Before You Operate
Reducing 4/8 to 1/2 before multiplying avoids inflated intermediate integers. The arithmetic is identical either way if you simplify at the end, but early reduction makes mistakes easier to spot.
GCD Is the Cleanup Step
After add/subtract/multiply/divide, divide numerator and denominator by gcd(|n|, |d|) and keep the denominator positive. That is the entire “simplify” algorithm most school problems need.
Try a fraction operation
Compare improper, mixed, and decimal views of the same rational:

- Common denominators are for addition and subtraction
- Division multiplies by the reciprocal
- Always finish with a positive-denominator lowest terms form
- Mixed numbers are for reading; improper forms are for chaining operations
