A fraction is in its simplest form when the greatest common factor of its numerator and denominator is 1
Dividing the numerator and denominator by a common factor is how you simplify a fraction.
i use a GCF to simplify a fraction by dividing it into both the numerator and the denominator.
It appears to be a complex fraction. Without some grouping symbols to explain which part of the larger fraction (numerator or denominator) has the fraction in it there is no way to simplify it.
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
When adding and subtracting unlike fractions, it is necessary to find a least common denominator. It's the same process as finding an LCM. You can simplify a fraction by finding the GCF of the numerator and denominator and dividing them both by it.
