Explanation:
To convert Fahrenheit to Celsius, the normal method is to subtract
So in our example:
#5/9(7032) = 5/9(38) = 190/9 = 21.bar(1)#
Alternatively, since
#5/9(70+40)40 = 5/9(110)40 = 550/9  40 = 61.bar(1)40 = 21.bar(1)#
The reverse conversion from Celsius to Fahrenheit can be done by either of the following:

Multiply by
#9/5# then add#32# . 
Add
#40# , multiply by#9/5# , then subtract#40# .
