Answer :
To convert 78°F to degrees Celsius, Barbara starts by subtracting 32 from 78. This gives her 46. The next step in the conversion process is to multiply this result by [tex]\( \frac{5}{9} \)[/tex].
Here's a breakdown of the steps:
1. Start with the temperature in Fahrenheit: 78°F.
2. Subtract 32: [tex]\( 78 - 32 = 46 \)[/tex].
3. Multiply the result by [tex]\( \frac{5}{9} \)[/tex]:
[tex]\[
46 \times \frac{5}{9} = 25.56
\][/tex]
Therefore, 78°F is approximately 25.56°C. So, the correct next step after subtracting 32 is to multiply 46 by [tex]\( \frac{5}{9} \)[/tex].
