18000lb greater then or less then 9t

It is equal because every 2000 pounds is 1 ton and 18000lb divided by 2000 equals 9.

No, 
Convert to same units then compare: If by ton you mean long ton (as used in UK): 1 t = 2240 lb → 9 t = 9 x 2240 lb = 20160 lb > 18000 lb

 If by ton you mean short ton (as used in USA): 1 t = 2000 lb → 9 t = 9 x 2000 lb = 18000lb which is not greater than 18000 lb as it is equal to 18000 lb.

Either way 18000lb which is not greater than 9T

The anwser is D 0.8
