------------------------------------------------ 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 a temperature from Fahrenheit to Celsius, you can use the formula:

[tex]\[ C = \frac{5}{9} \times (F - 32) \][/tex]

Barbara has already completed the first step of the conversion by subtracting 32 from 78, which results in 46. This simplifies our formula to:

[tex]\[ C = \frac{5}{9} \times 46 \][/tex]

The next step is to multiply 46 by [tex]\(\frac{5}{9}\)[/tex].

So, the next step in Barbara's conversion process is to multiply 46 by [tex]\(\frac{5}{9}\)[/tex].
