Answer:
600-90 lb bags of cement weigh 27 tons
Explanation:
You don't say how much each bag weighs. Let's suppose that that weight is 90 lb.
Then:
90 lb 1 ton
----------- * -------------- = 9/200 ton/bag
1 bag 2000 lb
Now multiply this by 600 bags:
9 tons 600 bags
--------------- * ------------------ = 27 tons
200 bags 1
600-90 lb bags of cement weigh 27 tons
