Question

The air temperature in degrees Fahrenheit (°F) can be converted to degrees Celsius (°C) by taking the temperature in degrees Fahrenheit, subtracting 32, and then dividing the result by 1.8 . Which equation can be used to convert °F to °C ? What is 77°F in °C ? (1 point) Responses
°F=1.8°C−32; 60.6°C
°F=1.8+°C+32; 43.2°C
°F−32=°C/1.8; 81°C
°F=1.8°C+32; 25°C

Answer 1

The correct equation to convert degrees Fahrenheit (°F) to degrees Celsius (°C) is:

\[
°C = \frac{(°F - 32)}{1.8}
\]

To find what 77°F is in °C, we can use the formula:

\[
°C = \frac{(77 - 32)}{1.8}
\]

Calculating it:

1. Subtract 32 from 77:
\[
77 - 32 = 45
\]

2. Divide the result by 1.8:
\[
\frac{45}{1.8} = 25
\]

So, 77°F is equal to 25°C.

Therefore, the correct options from the provided responses are:
- Equation: \(°F - 32 = °C / 1.8\)
- Temperature: \(25°C\)
