Question

barbara is converting 78°f to degrees celsius. first, she subtracts 32 from 78. what is the next step? multiply 46 by 5/9 multiply 46 by 9/5 add 273 to 46 subtract 273 from 46

Explanation:

Step1: Recall the formula for converting Fahrenheit to Celsius

The formula is \( C=\frac{5}{9}(F - 32)\), where \(C\) is the temperature in Celsius and \(F\) is the temperature in Fahrenheit.

Step2: Analyze the given operation

Barbara has already calculated \(F - 32=78 - 32 = 46\). According to the formula \(C=\frac{5}{9}(F - 32)\), after getting \(F - 32\) (which is 46), the next step is to multiply 46 by \(\frac{5}{9}\).

Answer:

multiply 46 by 5/9
