To multiply 4 pounds 1 ounce by 7, we first convert everything to ounces, perform the multiplication, and then convert back to pounds and ounces.
-
Convert 4 pounds 1 ounce to ounces:
- There are 16 ounces in a pound.
- So, \( 4 \text{ pounds} = 4 \times 16 = 64 \text{ ounces} \).
- Adding the additional 1 ounce: \( 64 + 1 = 65 \text{ ounces} \).
-
Multiply by 7:
- \( 65 \text{ ounces} \times 7 = 455 \text{ ounces} \).
-
Convert back to pounds and ounces:
- Divide 455 ounces by 16 to find the number of pounds: \[ 455 \div 16 = 28 \text{ pounds} \quad (\text{with a remainder}) \]
- Calculate the remainder: \[ 455 - (28 \times 16) = 455 - 448 = 7 \text{ ounces} \]
So, \( 4 \text{ pounds } 1 \text{ ounce} \times 7 = 28 \text{ pounds} \text{ } 7 \text{ ounces} \).
Final answer: 28 pounds 7 ounces.
