To convert a temperature from Celsius to Fahrenheit, you can use the formula:

[tex]\[ F = C \times \left(\frac{9}{5}\right) + 32 \][/tex]

Let’s solve this step by step for a Celsius temperature of 20 °C.

1. Identify the given temperature in Celsius:
- [tex]\( C = 20 \)[/tex] °C

2. Apply the conversion formula:
- [tex]\( F = 20 \times \left(\frac{9}{5}\right) + 32 \)[/tex]

3. Multiply 20 by (9/5):
- [tex]\( 20 \times 1.8 = 36 \)[/tex]

4. Add 32 to the result:
- [tex]\( 36 + 32 = 68 \)[/tex]

So, the equivalent temperature on the Fahrenheit scale is [tex]\( 68 \)[/tex] °F.

Thus, the correct answer is:
[tex]\[ \boxed{68\ °F} \][/tex]
