Which temperature conversion is correct for a temperature of 20 degrees Centigrade in degrees Fahrenheit?

To convert a temperature from degrees Celsius (Centigrade) to degrees Fahrenheit, the formula used is:

[ F = (C \times 9/5) + 32 ]

In this scenario, you want to convert 20 degrees Celsius to Fahrenheit. By applying the formula:

1. Multiply the Celsius temperature by 9/5:

[ 20 \times 9/5 = 36 ]

2. Then, add 32 to this result:

[ 36 + 32 = 68 ]

Thus, 20 degrees Celsius is equivalent to 68 degrees Fahrenheit. This conversion process confirms that the correct answer is indeed 68 degrees Fahrenheit.

The other temperature options do not result from the standard conversion formula applied to 20 degrees Celsius, underscoring that they do not align with the correct calculation.
