Afreight elevator has a weight limit of 2 tons. each crate that is loaded weighs 80 pounds. what is the greatest number of crates that can be loaded onto the elevator

step 1
convert pounds to ton
1 ton> 2204.62 lb
each crate weighs 80 pounds
so
by proportion
1/2204.62=x/80
x=80/2204.62> x=0.036 ton
each crate weighs 0.036 ton

step 2
divide 2 ton by 0.036
2/0.036=55.11 crate> 55 crate

the answer is
the greatest number of crates that can be loaded onto the elevator is 55 

alalternative method
step 1
convert ton to pounds 
1 ton> 2204.62 lb
a freight elevator has a weight limit of 2 ton
2 *2204.62 > 4409.24 lb

step 2
each crate weighs 80 pounds
divide 4409.24 by 80
4409.24/80=55.11 crate> 55 crate
