When the least common denominator is used in adding or subtracting fractions, is the result always a fraction in its simplest form?
No, not necessarily. The resulting fraction could still be simplified.
For example, if I take 1/4 + 2/8. The Lowest Common Denominator is 8.
2/8 + 2/8 = 4/8
But 4/8 is not the simplest form. 1/2 is.

What are simplest form for fractions?
If the GCF of the numerator and denominator is 1, the fraction is said to be in its simplest form.
How do you figure simplest forms of fractions?
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.
Why is it helpful to write a number as a product of primes?
Because it helps in reducing fractions to their simplest terms and finding the lowest common denominator when adding or subtracting fractions
How do I do simplest form on fractions?
Find the GCF of the numerator and the denominator. Divide them both by it. If the GCF is 1, the fraction is in its simplest form.
How do I write fractions in their simplest form?
Find the GCF of the numerator and denominator and divide them both by it. If the GCF is 1, the fraction is in its simplest form.
