Answer :
To convert degrees Fahrenheit to degrees Celsius, you can follow these steps:
1. Begin by subtracting 32 from the Fahrenheit temperature. In Barbara's case, this means subtracting 32 from 78:
[tex]\[
78 - 32 = 46
\][/tex]
2. The next step is to convert this result to Celsius by multiplying the difference by the fraction [tex]\( \frac{5}{9} \)[/tex]:
[tex]\[
46 \times \frac{5}{9}
\][/tex]
This step will give you the equivalent temperature in degrees Celsius. Therefore, after Barbara subtracts 32 from 78, the next step is to multiply 46 by [tex]\( \frac{5}{9} \)[/tex].
