Question 79081
{{{((2x-6))/21}}}
---------- =
{{{((5x-15))/21}}}
:
Remember, when you divide fractions, invert the dividing fraction and multiply
:
{{{((2x-6))/21}}} * {{{21/((5x-15))}}} = {{{(2(x-3))/21}}} * {{{21/(5(x-3))}}}: factored out the 2 & the 5:
:
Now you can cancel: the 21's and the (x-3)'s, leaving you with:
{{{2/5}}}
