Answer :
To convert a temperature from degrees Celsius to degrees Fahrenheit, you can use the following formula:
[tex]\[ \text{Temperature in Fahrenheit} (°F) = \left( \text{Temperature in Celsius} (°C) \times \frac{9}{5} \right) + 32 \][/tex]
Let's apply this formula to convert 21°C to Fahrenheit step-by-step.
1. Multiply the temperature in Celsius by 9/5:
[tex]\[
21°C \times \frac{9}{5} = 21 \times 1.8 = 37.8
\][/tex]
2. Add 32 to the result:
[tex]\[
37.8 + 32 = 69.8
\][/tex]
Therefore, a temperature of 21°C is equivalent to 69.8°F.
[tex]\[ \text{Temperature in Fahrenheit} (°F) = \left( \text{Temperature in Celsius} (°C) \times \frac{9}{5} \right) + 32 \][/tex]
