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

[tex]\[ \text{Celsius} = (\text{Fahrenheit} - 32) \times \frac{5}{9} \][/tex]

Let's apply this to the given temperature, which is [tex]\( 57^\circ \text{F} \)[/tex]:

1. Subtract 32 from the Fahrenheit temperature:
[tex]\[ 57 - 32 = 25 \][/tex]

2. Multiply the result by [tex]\(\frac{5}{9}\)[/tex]:
[tex]\[ 25 \times \frac{5}{9} = 13.888... \][/tex]

3. Round the result to the nearest whole number:
The value is approximately 13.89, so rounding to the nearest whole number gives you 14.

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