![### Conversion of Celsius to Fahrenheit
---
#### Question 2
Using the formula \( F = \frac{9}{5}C + 32 \), convert 20°C into degrees Fahrenheit.
\[ 20°C = \boxed{} °F \]
---
##### Explanation:
- The formula given is:
\[
F = \frac{9}{5}C + 32
\]
where:
- \( F \) is the temperature in degrees Fahrenheit,
- \( C \) is the temperature in degrees Celsius.
- **Step-by-Step Conversion:**
- Substitute \( C = 20 \) into the formula to find \( F \):
\[
F = \frac{9}{5}(20) + 32
\]
- Calculate the value:
\[
F = \frac{9}{5} \times 20 + 32
\]
\[
F = 36 + 32
\]
\[
F = 68
\]
- Thus, 20°C equals 68°F.
Remember to place 68 in the boxed area to complete the conversion.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F308ceb38-0706-4842-834f-0067ef9276f7%2Fcfd20ca7-53f2-4fad-a25e-c166156f8770%2Fywysc0c_processed.jpeg&w=3840&q=75)
