To convert 4 °F to °C and round the answer to the nearest whole number, follow these steps:
1. Subtract 32 from the Fahrenheit temperature:
[tex]\[
4 - 32 = -28
\][/tex]
2. Multiply the result by the fraction [tex]\(\frac{5}{9}\)[/tex]:
[tex]\[
-28 \times \frac{5}{9} \approx -15.555555555555557
\][/tex]
3. Round the result to the nearest whole number:
[tex]\[
-15.555555555555557 \approx -16
\][/tex]
So, the temperature 4 °F is approximately -16 °C when rounded to the nearest whole number.
