Convert the temperature of water from 12 degrees Celsius to degrees Fahrenheit.

To convert the temperature of water from degrees Celsius to degrees Fahrenheit, the formula used is:

[ F = \frac{9}{5}C + 32 ]

Where F is the temperature in degrees Fahrenheit and C is the temperature in degrees Celsius.

Using the provided temperature of 12 degrees Celsius, you would perform the following calculation:

1. Multiply 12 by ( \frac{9}{5} ):

[ \frac{9}{5} \times 12 = 21.6 ]

2. Add 32 to the result:

[ 21.6 + 32 = 53.6 ]

Therefore, converting 12 degrees Celsius to degrees Fahrenheit yields 53.6 degrees Fahrenheit, which corresponds to the first choice. This demonstrates the accuracy of using the Celsius to Fahrenheit formula correctly and obtaining the proper conversion.
