Frequently Asked Questions
What is the difference between numerator and denominator?
Why must the parts always be equal in a fraction?
A fraction only works when a whole is divided into strictly equal parts. If the pieces are of different sizes, we cannot use standard fractions to measure them.
How do I write one-third as a fraction?
One-third is written as 1/3, where 1 is the numerator and 3 is the denominator.
