To convert a temperature from Celsius to Fahrenheit, you use the formula:
[tex]\[ F = C \times \frac{9}{5} + 32 \][/tex]
Let's break down the steps using the given temperature of 20°C to illustrate the conversion:
1. Starting with the temperature in Celsius:
[tex]\[ C = 20 \][/tex]
2. Multiply the Celsius temperature by [tex]\(\frac{9}{5}\)[/tex]:
[tex]\[ 20 \times \frac{9}{5} = 20 \times 1.8 = 36 \][/tex]
3. Add 32 to the result to convert to Fahrenheit:
[tex]\[ 36 + 32 = 68 \][/tex]
So, 20°C is equivalent to 68°F.
Therefore, the correct answer is:
68°F
