To convert 20°C to Fahrenheit using the formula \( f = \frac{9}{5}c + 32 \):
1. Substitute \( c = 20 \) into the formula:
\[
f = \frac{9}{5} \times 20 + 32
\]
2. Calculate \( \frac{9}{5} \times 20 \):
\[
\frac{9 \times 20}{5} = \frac{180}{5} = 36
\]
3. Now add 32 to 36:
\[
f = 36 + 32 = 68
\]
Therefore, 20°C is \( 68.0°F \).
The correct answer is **68.0°F**.
