Question

A company that makes steel girders can produce 6 tons of girders in one day. How many pounds is this

Answer 1

That is 12,000 pounds.

1 ton = 2,000 pounds, so do 2,000 x 6

Answer 2

So, in order to do this we need to know how many pounds equal 1 ton.
1 ton=2,000 pounds.
Since we know this, than we multiply 6*2,000=12000. 
So, the company makes 12000 pounds of steel girders or 6 tons.
