Question 132759
Divide and simplify:
{{{((2z-2)/77)/((z-1)/(22z))}}}
Remember, to divide fractions, copy the first fraction, flip the divide sign to multiply and flip (invert) the second fraction.
{{{((2z-2)/77)*(22z/(z-1))}}} Now factor a 2 from the numerator of the first fraction:
{{{(2cross((z-1))/77)*(22z/cross((z-1)))}}} Now cancel the (z-1)'s leaving you with:
{{{(2/77)*(22z/1)}}} Now factor the denominator of the first fraction (77) and the numerator of the second fraction (22z):
{{{(2/(7*cross(11)))*((2*cross(11)*z)/1)}}} Cancel the 11's to leave you with:
{{{(2/7)*(2z/1)}}} Multiply.
{{{4z/7}}}...and there it is!
