Question 174308
Simplify:
{{{((4ab^5)/(a+b))/(6a^2b^4)}}} To divide fractions, you "copy-flip-flip" That is: Copy the first fraction, flip the sign from divide to multiply, flip (invert) the second fraction.
{{{((4a*b^5)/((a+b)))*(1/6a^2b^4)}}} Rewrite this after some factoring.
{{{((cross(2)*2*cross(a)*b*cross(b^4))/((a+b)))*(1/(cross(2)*3*cross(a)*a*cross(b^4)))}}} Cancel the indicated factors to get:
{{{2b/(3a(a+b))}}}
