8/32 factor out the 8 8*1/8*4 you can eliminate the 8 as it is a factor in both numerator and denominator 1/4 ---------simplest form
4/5 is in its simplest form.
You can factor a polynomial using one of these steps: 1. Factor out the greatest common monomial factor. 2. Look for a difference of two squares or a perfect square trinomial. 3. Factor polynomials in the form ax^2+bx+c into a product of binomials. 4. Factor a polynomial with 4 terms by grouping.
