Answer

Explanation:

Step1: Substitute C value

Given $C = 21$, use the formula $F=\frac{9}{5}C + 32$. Substitute $C = 21$ into the formula: $F=\frac{9}{5}\times21+32$.

Step2: Calculate $\frac{9}{5}\times21$

$\frac{9}{5}\times21=\frac{9\times21}{5}=\frac{189}{5}=37.8$.

Step3: Calculate the final F value

$F = 37.8+32$. So, $F=69.8$.

Answer:

$69.8$
