Adam can fit six large chocolate boxes or nine small chocolate boxes into a carton. How many cartons will he require to put sixty-six chocolate boxes into ?
9
Five cartons for large chocolate boxes = 5 * 6 = 30 chocolate boxes.
Four cartons for small chocolate boxes = 4 * 9 = 36 chocolate boxes.
Thus total number of cartons required = 5 + 4 = 9.
