Question

the temperature outside is 20.5 degrees centigrade. what is this temperature expressed in fahrenheit?

Answer 1

68.9

Explanation:

Let's take the formula: (C*9/5)+32=F

Now let's substitute C for 20.5:

(20*9/5)+32=F

36.9+32=F

68.9=F

So, 20.5 centigrade/celsuis is 68 temperature in fahrenheit.
