Aworker at a mill is loading 5-lb bags of flour into boxes to deliver to a local warehouse. each box holds 12 bags of flour. if the warehouse orders 3 tons of flour, how many boxes are needed to fulfill the order?

Well first think how many pounds are 1 ton?
but here it is 
1 ton = 2,000 pounds 
so they literally need 6,000 pounds of flour:/
now we gotta divide 6,000 by 5 
6,000/5 = 1,200
we now have to divide that number by 12 :)
1,200/12 = 100
they would need 100 boxes!!
hope this helps chu
