Question 260909
here is the problem
{{{((11x-55)/21) / ((x-5)/6x)}}}
step 1 - factor all parts to get
{{{(11(x-5)/21) / ((x-5)/6x)}}}
step 2 - multiply by the reciprocal to get
{{{(11(x-5)/21) * (6x/(x-5))}}}
step 3 - cancel (x-5) and reduce 6 and 21 by 3 to get
{{{(11/7) * (2x/1)}}}
step 4- multiply the numerator and denominator to get
{{{22x/7}}}
