How does the calculator simplify the result?

After performing the arithmetic, the result's numerator and denominator are both divided by their greatest common divisor (GCD), so the fraction shown is always in lowest terms.

What if the answer is an improper fraction?

The result is left as an improper fraction (numerator larger than denominator) alongside its decimal equivalent, rather than being converted to a mixed number.
