Frequently asked questions
How does simplifying a fraction work?
Divide top and bottom by their greatest common factor: 18/24 becomes 3/4 after dividing both by 6. The calculator computes that GCD itself and displays the steps, so you can repeat the method on paper. The position of the number on the number line is untouched.
Is 3/4 really equal to 6/8?
Yes — they are equivalent fractions describing the same amount. Simplifying divides both parts by the same number, which changes the look but never the value. Lowest terms is the standard final form in textbooks.
What about improper fractions like 7/4?
7/4 is already in lowest terms — the GCF of 7 and 4 is 1 — and it reads as the mixed number 1 3/4 in everyday use. Simplifying only changes numbers when numerator and denominator share a factor bigger than 1.
