Question

99.9°f = ______°c
please round your answer to the nearest tenth.

Explanation:

Step1: Recall conversion formula

The formula to convert Fahrenheit ($F$) to Celsius ($C$) is $C=\frac{5}{9}(F - 32)$.

Step2: Substitute the value of F

Substitute $F = 99.9$ into the formula: $C=\frac{5}{9}(99.9 - 32)$.
First, calculate $99.9-32 = 67.9$. Then $C=\frac{5}{9}\times67.9$.
$C=\frac{339.5}{9}\approx37.722$.

Step3: Round the result

Round $37.722$ to the nearest tenth, we get $37.7$.

Answer:

$37.7$
