Final answer:
To convert the child's temperature from Fahrenheit to Celsius, use the formula °C = (°F - 32) × 5/9. The child's temperature is approximately 37.0°C.
Step-by-step explanation:
To convert the child's temperature from Fahrenheit (°F) to Celsius (°C), we can use the formula:
°C = (°F - 32) × 5/9
Plugging in the given temperature of 98.6°F into the formula:
°C = (98.6 - 32) × 5/9
°C = 66.6 × 5/9
°C ≈ 37.0
Therefore, the child's temperature in °C is approximately 37.0°C.
