_________________________________________________________
There are: " 128 oz. " (in " 8 lbs." ) .
_________________________________________________________
Step-by-step explanation:
________________________________________________________
Set up a proportion; as a fraction; as follows:
________________________________________________________

400/ 25 = x / 8 ;

in which: "x" = the number of "ounces [oz.] there are in "8 lbs." ;
________________________________________________________
We shall solve for "x" , the answer to the problem:

Cross-factor multiply:

25x = (400) * 8 ;

→ 25x = 3200 ;

Divide each side of the equation by "25" ; to isolate "x" on one side of the equation; & to solve for "x" ;

→ 25x / 25 = 3200 / 25 ;

→ x = 128 .

Note of interest: " 16 oz. = 1 lb. " (exact conversion).

So; "8 lbs. = ? oz. " ;

→ " 8 lbs. * (16 oz/ 1 lb) = ( 8 * 16) oz. = 128 oz. ; → which is our answer!

Answer: 128 ounces

Step-by-step explanation: To convert 8 pounds into ounces, we will first need to find the conversion factor for pounds and ounces.

Conversion factor ⇒ 16 ounces = 1 pound

Next, notice that we are going from a larger unit "pounds" to a smaller unit "ounces." When we go from a larger unit to a smaller unit we multiply.

In this case, we will multiply 8 pounds by the conversion factor which is 16 and this will gives us 128 ounces.

This means that 8 pounds is equal to 128 ounces.
