Answer :
To convert a temperature from degrees Fahrenheit to degrees Celsius, you can use the formula:
[tex]\[ C = (F - 32) \times \frac{5}{9} \][/tex]
Let’s apply this formula step by step to convert [tex]\(78^{\circ} F\)[/tex] to degrees Celsius:
1. Subtract 32 from the Fahrenheit temperature:
Start with 78 and subtract 32:
[tex]\[ 78 - 32 = 46 \][/tex]
So, after this step, we have 46.
2. Multiply the result by [tex]\( \frac{5}{9} \)[/tex]:
Now, take the result from the first step (which is 46) and multiply it by [tex]\( \frac{5}{9} \)[/tex]:
[tex]\[ 46 \times \frac{5}{9} = 25.5555 \ldots \][/tex]
This means that [tex]\(78^{\circ} F\)[/tex] is approximately [tex]\(25.56^{\circ} C\)[/tex].
Therefore, after Barbara subtracts 32 from 78, the next step is to multiply 46 by [tex]\( \frac{5}{9} \)[/tex].
[tex]\[ C = (F - 32) \times \frac{5}{9} \][/tex]
