how much does actual dog food weigh?

Question

case of food weighs 52 pounds  7 oz, packaging weighs 3 pounds 11 oz

Answer 1

Subtract the weight of the packaging from the weight of the case to get the weight of the food.

 

(52 lbs + 7 oz) - (3 lbs + 11 oz) = (51 lbs + 23 oz) - (3 lbs + 11 oz)

 

= (51 - 3)lbs + (23 - 11)oz = ? lbs ? oz

 

You can finish from here.
