Answer :

Final answer:

To subtract 12 ounces from 4 pounds, convert 4 pounds to ounces (64 ounces), subtract 12 ounces, and then convert back to pounds and ounces to get the result: 3 pounds, 4 ounces.

Explanation:

The question involves subtracting customary units of weight, specifically subtracting ounces from pounds. To solve this problem, we will convert pounds to ounces and then perform the subtraction.

  1. First, we need to know the conversion factor between pounds and ounces. One pound is equivalent to 16 ounces.
  2. To subtract 12 ounces from 4 pounds, first convert 4 pounds to ounces. Multiply 4 (pounds) by 16 (ounces per pound) to get 64 ounces.
  3. Now subtract 12 ounces from 64 ounces to find the final weight in ounces. 64 ounces - 12 ounces = 52 ounces.
  4. To convert back to pounds and ounces, divide 52 by 16 (since 16 ounces is 1 pound). 52 ÷ 16 = 3 pounds with a remainder of 4 ounces. So, the final answer is 3 pounds, 4 ounces.

Therefore, when you subtract 12 ounces from 4 pounds, you end up with 3 pounds, 4 ounces
