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

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

Here's how you can convert [tex]\( 57^\circ F \)[/tex] to Celsius:

1. Subtract 32 from the Fahrenheit temperature:

[tex]\[ 57 - 32 = 25 \][/tex]

2. Multiply the result by [tex]\(\frac{5}{9}\)[/tex] to convert to Celsius:

[tex]\[ 25 \times \frac{5}{9} = \frac{125}{9} \][/tex]

3. Calculate the division:

[tex]\[ \frac{125}{9} \approx 13.89 \][/tex]

4. Round the result to the nearest whole number:

13.89 rounds to 14

Therefore, the temperature [tex]\( 57^\circ F \)[/tex] is approximately [tex]\( 14^\circ C \)[/tex] when rounded to the nearest whole number.
