A. 278382 ounces

B. 43 ounces

C. 64.1 ounces

Answer 2

Answer: a) 278382 oz

b) 43 oz

c) 64.1 oz

Explanation:

a) 8 T. 1,398 lb. 14 oz. × 6

First we need to change it in 'oz'.

As we know that

`1\ ton=32000\ oz\\\\1\ lb=16\ oz`

so, it becomes,

`8* 32000+1398* 16+14\ oz\\\\=278382\ oz`

8 T. 1,398 lb. 14 oz. × 6 becomes

`278382* 6\\\\=1670292\ oz`

b) 349 lb. 6 oz. ÷ 130

It becomes,

`349* 16+6\ oz\\\\=5590\ oz\\\\\text{ at last it becomes}\\\\=(5590)/(130)\\\\=43\ oz`

c) 6 T. 294 lb. ÷ 3,071

First it becomes,

`6* 32000+294* 16\ oz\\\\=196704\ oz`

At last it becomes,

`(196704)/(3071)\\\\=64.1\ oz`

Hence, a) 278382 oz

b) 43 oz

c) 64.1 oz
