Dividing Fractions Test

When we divide fractions, we leave the first fraction unchanged (fraction on the left). We then take the reciprocal of the second fraction (fraction on the right). Once this is done, we multiply. Take the result and simplify by canceling the Greatest Common Divisor from the numerator and denominator.
