## Algebra 1

In order to simplify, we want something to be both in the numerator and the denominator of the fraction so it can be canceled out. Thus, we factor and obtain: $(2m-5) / (6m-15) \\\\ (2m-5)/3(2m-5) \\\\ 1/3$ m cannot equal 2.5, for if m equaled 2.5, the denominator of the fraction would cancel out to 0, which is not allowed.
