Question

The formula for converting temperature from Fahrenheit(F) to Celsius(C) is C = - (F - 32). If the temperature is 7° Fahrenheit, what is it in Celsius?

a) 0°C
b) 25°C
c) 45°C
d) 605°C

Answer 1

The closest answer from the options provided would be (a) 0°C, but since none of the choices is correct based on the actual calculation we've done, none of these options is an accurate representation of 7°F in Celsius.

Step-by-step explanation:

The formula given in the question is incorrect. The correct formula to convert from Fahrenheit to Celsius is: C = (F - 32) × 5/9.

Let's solve it step by step. We want to convert 7°F to Celsius.

Step 1: Subtract 32 from the Fahrenheit temperature.

7 - 32 = -25

Step 2: Multiply the result by 5/9.
-25 × 5/9

Step 3: Carry out the multiplication.
-25 × 5/9 = -125/9

Step 4: To make this division clearer, let's divide 125 by 9.
125/9 = 13.888....

Since we are dealing with a negative temperature difference, we should also make the result negative:

-13.888...

Step 5: Round the result (if necessary). We can round it to one or two decimal places, depending on how precise we want the result to be.

The continuous decimals suggest that the temperature has an infinite decimal expansion in this context, but for practical purposes, it is often rounded.

So, the temperature in Celsius when it is 7°F is approximately -13.89°C (rounded to two decimal places).
