Your discussion looks OK so far.  Suggest that you both think about labels and units of measurement.

5.4 divided by 9 means what?  This makes more sense if you include units:  5.4 hours to make 9 parts.  From this info we can obtain the rate at which the parts are made.  That would have units of measurement "parts made per hour," or parts/hr.  5.4 hours / 9 parts makes less sense; the result of that would have units of measure "hours."

Once you have the rate at which these parts are made, multiply that rate by 25.8 hours.
