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 degrees Fahrenheit to degrees Celsius, Barbara needs to follow these steps:

1. Subtract 32 from the Fahrenheit temperature:
- Start with the temperature in Fahrenheit, which is 78°F.
- Subtract 32 from this temperature:
[tex]\(78 - 32 = 46\)[/tex].

2. Multiply the result by [tex]\( \frac{5}{9} \)[/tex]:
- After subtracting 32, the result is 46.
- To convert this result to Celsius, multiply by [tex]\( \frac{5}{9} \)[/tex]:
[tex]\( 46 \times \frac{5}{9} \)[/tex].

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