Question 581482
{{{(-7+7w)/5}}} divided by {{{(9w-9)/25}}}
When diving fractions, you invert the second fraction and change the operation to multiply, so...
{{{((-7+7w)/5)*(25/(9w-9))}}} Rewrite the numerator of first fraction:{{{-7+7w = (7w-7)}}}
{{{((7w-7)/5)*(25/(9w-9))}}} Cancel a 5.
{{{(7w-7)*(5/(9w-9))}}} Now factor a 7 from the numerator of the first fraction and a 9 from the denominator of the second fraction.
{{{7(w-1)*5/(9*(w-1))}}} Cancel the {{{(w-1)}}}'s
{{{7*5/9}}} Simplify.
{{{35/9}}} = {{{3.9}}}
