a common numerator is a fraction result to common denominator
They are a common factor and any common factor in the numerator and denominator of a ratio can be cancelled out.
If the numerator and denominator are prime numbers and not equal then they don't have common factors (except 1 which would be a common factor even if the numerator and denominator were prime numbers).
When the numerator is less than the denominator then it is a common fraction but if the numerator is greater than the denominator then it is an improper fraction.
Dividing the numerator and denominator by a common factor is how you simplify a fraction.
If the numerator and denominator of a fraction have a common factor (except for '1'), divide both numerator and denominator by their common factor. The fraction is in the simplest form when the numerator and denominator have no common factors.
If the numerator was a factor of the denominator.
I'm not sure finding a common numerator will help you very much. The common denominator of those two numbers is 420.
You look for common factors in the numerator and the denominator, then divide both the numerator and the denominator by that common factor.
There's no such thing as a least common numerator and even if there were, you'd need two of them to find something in common between them.
An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.
Common numerator of 1/2 and 3/10(multiply 1/2 by 3)3/6 and 3/10 now have common numerators
If the highest common factor of the numerator and denominator of a fraction is 1 then the fraction is in its simplest form.
