c%2Fb-c%2F%28abc%29 Start with the given expression.


%28c%2Aac%29%2F%28b%2Aac%29-c%2F%28abc%29 Multiply the first fraction by ac%2Fac to get the denominators equal


%28ac%5E2%29%2F%28abc%29-c%2F%28abc%29 Multiply


%28ac%5E2-c%29%2F%28abc%29 Combine the fractions


%28c%28ac-1%29%29%2F%28abc%29 Factor out the GCF from the numerator


%28cross%28c%29%28ac-1%29%29%2F%28ab%2Across%28c%29%29 Cancel out like terms.


%28ac-1%29%2F%28ab%29 Simplify


So c%2Fb-c%2F%28abc%29=%28ac-1%29%2F%28ab%29 where a%3C%3E0, b%3C%3E0 or c%3C%3E0
