Reducing Fractions (Simplest Form) A fraction is in simplest form if the greatest common factor (GCF) of its numerator and denominator is 1 — that is, if they share no common factors other than 1 .
What do we call a fraction that has a 1 in the numerator?
Fractions with numerator 1 are called unit fractions. Proper fractions. Fractions in which the numerator is less than the denominator are called proper fractions. Improper fractions. Fractions in which the numerator is more than or equal to the denominator are called improper fractions.
How do you divide a numerator and denominator by the same number?
If you multiply both the numerator and denominator of a fraction by the same non-zero number, the fraction remains unchanged in value. Therefore, equivalent fractions can be created by multiplying (or dividing) the numerator and denominator by the same number. This number is referred to as a multiplier.
Does dividing the numerator and denominator by a common factor guarantee that the result will be in simplest form?
To simplify a fraction to lowest terms, divide both the numerator and the denominator by their common factors. Repeat as needed until the only common factor is 1. Simplify . Although is an equivalent fraction to , it is not in lowest terms.
What is a fraction that Cannot be simplified?
If a fraction cannot be simplified, it means there is no common factor between numerator and denominator. But 1 is a factor of every number. Hence, the only common factor between numerator and denominator is 1 . As the only common factor between numerator and denominator is 1 , Greatest Common Factor too is 1 .
What are the 7 types of fraction?

Is there an integer by which fractions are evenly divisible?
Another way of saying this is that there is no integer by which the numerator and denominator are both evenly divisible. For instance, the fraction is in lowest terms because there is no integer by which both 1 and 3 are evenly divisible.
Why are fractions not in the lowest terms?
1 1 = 1 and 3 1 = 3-dividing numerator and denominator by 1 does not change the fraction.) On the other hand, the fraction is not in lowest terms because 100 and 300 are both evenly divisible by 100. If we perform this division, we are left with an equivalent fraction () in lowest terms.
How are the numerator and the denominator of a fraction related?
In positive common fractions, the numerator and denominator are natural numbers. The numerator represents a number of equal parts, and the denominator indicates how many of those parts make up a unit or a whole. The denominator cannot be zero, because zero parts can never make up a whole.
How can you tell if two fractions are the same?
Solution: In each case, we can determine if the fractions are equivalent by checking to see if the same number multiplied by both the numerator and denominator of one fraction gives us the other fraction. For instance, in part a, if we multiply both the numerator and denominator of by 3, we get . Thus, these fractions are equivalent.
