divide 4/x^8 by 16/x^5
When dividing fractions we multiply by the reciprocal. (In English, flip the second fraction over and multiply.)
%284%2Fx%5E4%29%2A%28x%5E5%2F16%29
4x%5E5%2F%2816x%5E4%29
4x%5E4%2Ax%2F%284%2A4x%5E4%29 Find the numerator and denominator's like factors.
cross%284x%5E4%29%2Ax%2F%284%2Across%284x%5E4%29%29 Cancel them, because a/a=1
highlight%28x%2F4%29
Happy Calculating and Happy Thanksgiving!!!

Think back to how you did division of fractions. Invert the divisor (finds its reciprocal) and change the sign to multiply. So this problem could be written as
%284%2Fx%5E8%29+%2A%28x%5E5%2F16%29
%284%2Ax%5E5%29%2F%28x%5E8%2A16%29 Divide top and bottom by 4
x%5E5%2F%28x%5E8%2A4%29Divide top and bottom by x^5
1%2F%284x%5E3%29
