Understand the relationship between Celsius and Fahrenheit temperature scales. The conversion formula is: \(F = \frac{9}{5}C + 32\).
Identify the given temperature in Celsius, which is 20°C, and substitute it into the formula to find the equivalent Fahrenheit temperature.
Calculate the Fahrenheit temperature by multiplying 20 by \(\frac{9}{5}\) and then adding 32: \(F = \frac{9}{5} \times 20 + 32\).
Simplify the expression step-by-step: first multiply, then add to find the Fahrenheit value corresponding to 20°C.
Compare the calculated Fahrenheit temperature with the options provided to determine which one matches 20°C.
