%28%282x-6%29%29%2F21
---------- =
%28%285x-15%29%29%2F21
:
Remember, when you divide fractions, invert the dividing fraction and multiply
:
%28%282x-6%29%29%2F21 * 21%2F%28%285x-15%29%29 = %282%28x-3%29%29%2F21 * 21%2F%285%28x-3%29%29: factored out the 2 & the 5:
:
Now you can cancel: the 21's and the (x-3)'s, leaving you with:
