------------------------------------------------ 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 follow these steps:

1. Start with the Fahrenheit temperature. In this case, it's [tex]\( 78^\circ F \)[/tex].

2. Subtract 32 from the Fahrenheit temperature. So, you calculate [tex]\( 78 - 32 \)[/tex], which equals 46.

3. The next step is to multiply the result by [tex]\( \frac{5}{9} \)[/tex] to convert the temperature to degrees Celsius. So you take 46 and multiply it by [tex]\( \frac{5}{9} \)[/tex].

So, after subtracting 32 from 78, the next step Barbara should take is to multiply 46 by [tex]\( \frac{5}{9} \)[/tex].
