Answer :
To convert temperatures from Fahrenheit to Celsius, you can use the formula:
[tex]\[ C = \frac{5}{9} \times (F - 32) \][/tex]
Where:
- [tex]\( C \)[/tex] is the temperature in degrees Celsius.
- [tex]\( F \)[/tex] is the temperature in degrees Fahrenheit.
Barbara starts by subtracting 32 from 78 Fahrenheit. Here's how to proceed:
1. Subtract 32 from the Fahrenheit temperature:
[tex]\( 78 - 32 = 46 \)[/tex]
2. Multiply the result by [tex]\(\frac{5}{9}\)[/tex]:
[tex]\( 46 \times \frac{5}{9} = 25.56 \)[/tex] (approximately)
So, after subtracting 32 from 78, the next step is to multiply 46 by [tex]\( \frac{5}{9} \)[/tex]. This converts the temperature from Fahrenheit to Celsius.
[tex]\[ C = \frac{5}{9} \times (F - 32) \][/tex]
Where:
- [tex]\( C \)[/tex] is the temperature in degrees Celsius.
- [tex]\( F \)[/tex] is the temperature in degrees Fahrenheit.
