A fraction is considered a unit fraction if its numerator is 1 and its denominator is a positive integer. In simpler terms, a unit fraction represents one part of a whole that has been divided into equal parts.
To determine if a given fraction is a unit fraction, follow these steps:
- Check the numerator: If the numerator is 1, then it’s a candidate for a unit fraction.
- Check the denominator: Ensure that the denominator is a positive integer (meaning it’s greater than zero).
For example, the fraction 1/5 is a unit fraction because it has a numerator of 1 and a denominator of 5, which is a positive integer. On the other hand, the fraction 3/5 is not a unit fraction because its numerator is not 1.
In summary, whenever you see a fraction in the form of 1/n (where n is a positive integer), you can confidently say that it is a unit fraction.
