Subtract 4 ounces from 5 pounds.

A. 3 lb., 12 oz.
B. 5 lb., 6 oz.
C. 4 lb., 12 oz.
D. 3 lb., 8 oz.

Answer :

Answer is 4 lb.,12 oz.

As one pound has 16 ounces.
When we convert the given 5 lb. into ounces we multiply it by 16.

5 lb = 5 x 16 oz
5 lb = 80 oz

When we subtract 4 oz from 80 oz
We get
80 - 4 = 76 oz
Which is
64 oz + 12 oz
(16 x 4) oz + 12 oz
Which will be
4 lb. + 12 oz
So the answer will be
4 lb., 12 oz.

Final answer:

To subtract 4 ounces from 5 pounds, first convert 5 pounds to ounces (5 x 16 = 80 ounces), then subtract the 4 ounces to get 76 ounces. Next, convert 76 ounces back to pounds and ounces to get the answer, which is 4 pounds and 12 ounces.

Explanation:

The student asked to subtract 4 ounces from 5 pounds. To solve this problem, we need to understand the conversion between pounds and ounces. Since there are 16 ounces in one pound, we multiply the number of pounds by 16 to find the equivalent number of ounces. Therefore, 5 pounds equals 80 ounces (5 x 16 = 80). To subtract the 4 ounces, we take the total number of ounces in 5 pounds, which is 80, and subtract 4 to get 76 ounces. Now, we have 76 ounces after the subtraction.

After that, to convert 76 ounces back to pounds and ounces, divide 76 by 16. This gives us 4 pounds with 12 ounces remaining because 76 divided by 16 is 4 with a remainder of 12. This subtracts customary units of weight and gives us the final answer: 4 pounds and 12 ounces.
