Answer 1

a. 995 lb. 6 oz.

+ 1,004 lb. 11 oz.

______________

1999 lb 17 oz = 2000 lb 1 oz.

16 oz = 1 lb

Therefore,

1999 lb 17 oz = 1999 lb + 16 oz + 1 oz = 1999 lb + 1 lb + 1 oz

= 2000 lb. 1 oz.

_______________________________________________

b. 24 T 1,507 lb 12 oz.

+ 7 T 938 lb 6 oz.

______________

31 T 2445 lb 18 oz

2000 lb = 1 T.

16 oz = 1 lb

Therefore,

31 T 2445 lb 18 oz = 31 T + 2000 lb + 445 lb + 16 oz + 2 oz

= 31 T + 1 T + 445 lb + 1 lb + 2 oz

= 32 T. 446 lb. 2 oz.

_______________________________________________

c. 6 T. 14 oz.

+ 11 T. 1,949 lb.

+ 8 oz.

+ 5 T. 49 lb. 15 oz.

______________________

22T. 1998 lb. 37 oz.

22T. 1998 lb. 37 oz. = 22 T + 1998 lb + 16oz + 16 oz + 5 oz.

= 22 T + 1998 lb + 1 lb + 1 lb + 5 oz.

= 22 T + 2000 lb + 5oz

= 22 T + 1 T + 5 oz.

= 23T. 5oz.
