Rewrite the division as a multiplication.
72/18=72/18=72*1/4
Type a fraction. is this right

Your symbolism is absolutely not standard.
For instance,
what happened to the negative sign in the denominator?
72/18=72/18 is just not true.
Secondly,
This is silly. How can 18 be 4?
72/18=72*1/4
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.
