To determine if Juanita's conversion from kilograms to ounces is correct, we first need to convert kilograms to pounds, and then convert pounds to ounces.

Step 1: Convert kilograms to pounds. Using the conversion factor:

  • 1 kilogram = 2.21 pounds

So for 3 kilograms: \[ 3 \text{ kg} \times 2.21 \text{ lb/kg} = 6.63 \text{ lb} \]

Step 2: Convert pounds to ounces. Using the conversion factor:

  • 1 pound = 16 ounces

Now we convert 6.63 pounds to ounces: \[ 6.63 \text{ lb} \times 16 \text{ oz/lb} = 106.08 \text{ oz} \]

Therefore, 3 kilograms is equal to 106.08 ounces.

If Juanita got a different answer, then her conversion is incorrect. However, if she also arrived at approximately 106.08 ounces, then her conversion is correct.
