Answer :

To convert a temperature from Fahrenheit to Celsius, you can follow these steps:

1. Start with the Fahrenheit temperature: In this case, Barbara is starting with 78 degrees Fahrenheit.

2. Subtract 32 from the Fahrenheit temperature: She begins by subtracting 32 from 78. This gives her 46.

3. Multiply the result by 5/9: The next step, which is crucial in the conversion process, is to multiply the result by 5/9. This step converts the adjusted Fahrenheit value into Celsius.

Therefore, after subtracting 32 from 78, Barbara should multiply 46 by 5/9. This will complete the conversion from Fahrenheit to Celsius.
