Rewrite the division as a multiplication.
Type a fraction. is this right
Your symbolism is absolutely not standard.
what happened to the negative sign in the denominator?
72/-18=72/18 is just not true.
This is silly. How can 18 be 4?
What would be wrong with 72* 1/18 ? (assuming the sign was right, which I think it is not)
Surely your text has examples on this.
