in science class, richard learns that petrol has a boiling point of 203° fahrenheit. his teacher asks him to convert this temperature to degrees celsius. what is the boiling point of petrol in degrees celsius?
95°c
130.6°c
307.8°c
397.4°c

Explanation:

Step1: Recall conversion formula

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

Step2: Substitute given value

Substitute $F = 203$ into the formula: $C=\frac{5}{9}(203 - 32)$.

Step3: Calculate inside parentheses first

$203-32 = 171$, so $C=\frac{5}{9}\times171$.

Step4: Perform multiplication

$\frac{5}{9}\times171=5\times19 = 95$.

Answer:

$95^{\circ}C$
