Answer

Explanation:

Step1: Recall temperature - conversion formula

The formula to convert Fahrenheit ($F$) to Celsius ($C$) is $C=\frac{5}{9}(F - 32)$. Barbara has already found $F - 32=78 - 32 = 46$.

Step2: Determine the next step

According to the formula, after getting $F - 32$, the next step is to multiply the result by $\frac{5}{9}$. So she should multiply 46 by $\frac{5}{9}$.

Answer:

multiply 46 by 5/9
