Dividing the numerator and denominator by a common factor is how you simplify a fraction.
When the GCF of the numerator and the denominator is 1.
Yes. When the numerator and denominator have a GCF of 1, the fraction is in the simplest form. To simplify, find the GCF and divide both numerator and denominator by the same: Example: simplify 30/40 30/40 divided by 10/10 (1) = 3/4
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).
A percentage
yea
YES a fraction can be a denominator.
Yes, it is.
A binomial and possibly a fraction.
Yes, it is.
The denominator should be the same as the denominator of the fraction.
the denominator
The denominator tells you the total of the pieces in the fraction.
you multiply the numerator by the numerator and the denominator by the denominator.
The upper part of a fraction is its numerator and the lower part of a fraction is its denominator.
The denominator is the number underneath the numerator in a fraction as for example in the fraction 3/4 the numerator is 3 and the denominator is 4
