In this last lesson, we developed a function that will find the GCD of two numbers. It turns
out when you "reduce a fraction to lowest terms," you are really dividing both the numerator and denominator
by the GCD. So we'll do that here: program a simple "fraction reducer" using the GCD function from the last lesson.

But, there's a small issue. Remember in the `gcd(a,b)`

function that the first argument (a) must be less than the second
argument (b). To be sure our fraction reducer will always work, let's write a "wrapper function" called `get_gcd`

that will
ensure that the main `gcd`

function gets called with the lower number first.

`if`

statement to compare a and b, and the two `gcd`

function calls to ensure that
`gcd(a,b)`

always gets called with $a< b$.

This code will not run! You have to do two things. First, figure out what condition you'll put in the

`if`

statement
to check on the relative size of a vs. b. Next, given the answer to your condition, in what order will you
place a and b in the `gcd`

calls? It'll be either `gcd(a,b)`

or `gcd(b,a)`

. See if you can figure
out which goes where.
