Barbara is converting [tex]78^{\circ} F[/tex] to degrees Celsius. First, she subtracts 32 from 78. What is the next step?

A. Multiply 46 by [tex]\frac{5}{9}[/tex]
B. Multiply 46 by [tex]\frac{9}{5}[/tex]
C. Add 273 to 46
D. Subtract 273 from 46

Answer :

To convert [tex]$78^{\circ} F$[/tex] to degrees Celsius, Barbara starts by subtracting 32 from 78. This gives her 46.

The next step is to convert this adjusted temperature from Fahrenheit to Celsius. To do that, she needs to multiply the result by [tex]\( \frac{5}{9} \)[/tex].

So, the next step is:
Multiply 46 by [tex]\( \frac{5}{9} \)[/tex].
