Question

The formula to convert °C to °F is:

Answer 1

Answer:

80.6

Step-by-step explanation:

F = 9/5 C + 32

F = (9/5)*27 + 32               Substitute 27 into the equation

F = 243 / 5  + 32               Multiply 9 and 27 together  

F = 48.6 + 32                     Divide by 5

F = 80.6                             Add on 32

A very quick way to do this is to double your centigrade temperature and and 30 which you should be able to do in your head.

2*27 = 54 Add 30

54 + 30 = 84

This quick way will tell you if you get near the right answer.
