Last Question

Because this may not be the question you want, I'll omit the first step which should be done with latex. The key to all of these except C is to invert the second fraction (turn the second fraction upside down) and multiply.

A

\dfrac{6}{5} * \dfrac{-2}{3}

=(6*-2) / (5*3) = - 12/15 = -4/5

B

\dfrac{7}{4} *\dfrac{5}{3}

= (7*5) / (4*3) = 35 / 12 = 2 11/12

C

Impossible to do 4/0 cannot be done.

D

\dfrac{-2}{3} /\dfrac{-5}{4}=\dfrac{-2}{3} *\dfrac{-4}{5}

= (-2*-4)/(3*5) =

8/15
