Answer :
To convert from Fahrenheit to Celsius, we first use the formula:
[tex]$$
C = \frac{5}{9} \left(F - 32\right)
$$[/tex]
Starting with [tex]$78^\circ F$[/tex], Barbara subtracts 32 from it:
[tex]$$
78 - 32 = 46
$$[/tex]
The next step is to multiply the result by [tex]$\frac{5}{9}$[/tex] to complete the conversion:
[tex]$$
46 \times \frac{5}{9}
$$[/tex]
Thus, after subtracting 32, the next step is to multiply 46 by [tex]$\frac{5}{9}$[/tex].
