Answer: °C = 4.44°C
Explanation: The centigrade scale and Fahrenheit scale are related by the formulae below
9 *°C = 5(°F - 32)
Where °C = measurement of temperature in centigrade scale.
°F = measurement of temperature in Fahrenheit scale =40°F
By substituting the parameters, we have that
9 * °C = 5 (40 - 32)
9* °C = 5(8)
9 * °C = 40
°C = 40/9
°C = 4.44°C
