Answer 2

Answer:

A.) Multiply 46 by 5/9

Step-by-step explanation:

The formula to convert Fahrenheit degrees to Celsius degrees is as follows:

$\\ C = \frac{5}{9}*(F-32)$

So, converting 78°F to °C, according this previous equation is:

$\\ C = \frac{5}{9}*(78-32)$ [Barbara subtracts 32 from 78]

$\\ C = \frac{5}{9}*(46)$  [Barbara multiplies 46 by 5/9]

$\\ C = \frac{5*46}{9}$

$\\ C = \frac{230}{9} = 25.56$ or 25.56°C
