Answer :
To convert a temperature from degrees Fahrenheit to degrees Celsius, you should follow these steps:
1. Subtract 32: Start with the temperature in Fahrenheit. In this case, Barbara is starting with 78°F. She subtracts 32 from 78, which equals 46.
2. Multiply by [tex]\(\frac{5}{9}\)[/tex]: After getting 46 from the first step, the next step is to convert the result to Celsius. To do this, you multiply 46 by [tex]\(\frac{5}{9}\)[/tex].
Therefore, the correct next step for Barbara, after subtracting 32, is to multiply 46 by [tex]\(\frac{5}{9}\)[/tex]. This will give her the temperature in degrees Celsius.
