Question

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 397.4°c 130.6°c 307.8°c

Explanation:

Step1: Recall the conversion formula

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

Step2: Substitute the value of $F$

Given $F = 203$, substitute it into the formula: $C=\frac{5}{9}(203 - 32)$.
First, calculate the value inside the parentheses: $203-32 = 171$.
Then, calculate $C=\frac{5}{9}\times171$.
Since $171\div9 = 19$, and $19\times5=95$.

Answer:

$95^{\circ}C$
