Add both the eqs.
So it becomes A+B<B+C
≡ A<C

You could also use the Transitive Property of Inequalities and state that if A<B and B<C, then A<C. This is true because the same sign, the less than sign, is used for all inequalities and the same variable B is being used as the median. You could write this equation as A<B<C.
