An outside thermometer reads [tex]$57^{\circ} F$[/tex]. What is this temperature in [tex]^{\circ}C[/tex]? Round your answer to the nearest whole number.



A. 14

B. 49

C. 71

D. 135

Answer :

To convert from Fahrenheit to Celsius, we use the formula:

$$
C = \frac{5}{9}(F - 32)
$$

Given that the temperature in Fahrenheit is $57^\circ F$, we follow these steps:

1. Subtract $32$ from the Fahrenheit temperature:

$$
57 - 32 = 25
$$

2. Multiply the result by $\frac{5}{9}$:

$$
C = \frac{5}{9} \times 25 \approx 13.89
$$

3. Finally, round the result to the nearest whole number:

$$
13.89 \approx 14
$$

Thus, the temperature in Celsius is approximately $14^\circ C$.
