To determine if Juanita's conversion of 3 kilograms to ounces is correct, let's first break down the conversion process step by step.

  1. Convert kilograms to pounds:
    Since there are 2.21 pounds in a kilogram, we first convert 3 kilograms to pounds: \[ 3 \text{ kg} \times 2.21 \text{ lb/kg} = 6.63 \text{ lb} \]

  2. Convert pounds to ounces:
    There are 16 ounces in a pound, so we convert the 6.63 pounds to ounces: \[ 6.63 \text{ lb} \times 16 \text{ oz/lb} = 106.08 \text{ oz} \]

Therefore, 3 kilograms is equal to approximately 106.08 ounces.

If Juanita provided a different answer, we can conclude that her conversion is incorrect. If she provided the calculated value (106.08 ounces), then her conversion is indeed correct.
