Question

Explain how to simplify the expression 5m/3+-2m/3

Answer 1

Here we have a fraction sum, specifically an homogeneous fraction. Simply we have to subtract the positives with negatives; which are going to give us the answer:

$\frac{5m}{3} + \frac{ - 2m}{3} = \frac{3m}{3} = m$

we can simplify those 3s, giving a result of m
