Answer :
To convert a temperature from Fahrenheit to Celsius, you can use the formula:
[tex]\[ \text{Celsius} = (\text{Fahrenheit} - 32) \times \frac{5}{9} \][/tex]
For Barbara's problem, let's go through the steps one by one:
1. Start with the given Fahrenheit temperature: 78°F.
2. Subtract 32 from the Fahrenheit temperature:
[tex]\[ 78 - 32 = 46 \][/tex]
3. The next step is to multiply this result by [tex]\( \frac{5}{9} \)[/tex]:
[tex]\[ 46 \times \frac{5}{9} \][/tex]
This step will give you the temperature in degrees Celsius. Therefore, the next step is to multiply 46 by [tex]\( \frac{5}{9} \)[/tex].
[tex]\[ \text{Celsius} = (\text{Fahrenheit} - 32) \times \frac{5}{9} \][/tex]
