Problem 3
We are adding fractions, so we need common denominators. We don't have common denominators, so we have to find a common denominator. First factor both denominators.

A metric on a set of objects defines a measure of distance on the set, that is, for each pair of objects it defines the distance between those objects. Formally a metric is a function \(d\) from
pairs of elements of the set to the non-negative real numbers satisfying,
1. \(d(a,b) = 0\) if and only if \(a=b\),
