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 degrees Fahrenheit to degrees Celsius, you can follow these steps:

1. Subtract 32 from the Fahrenheit temperature.
- Barbara has already done this part by subtracting 32 from 78, which results in 46.

2. Multiply the result by the conversion factor [tex]\( \frac{5}{9} \)[/tex].
- Next, you take the result of 46 and multiply it by [tex]\( \frac{5}{9} \)[/tex].

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