How do you change from Fahrenheits to Celsius such as 77f

For this, you take the Fahrenheit number, subtract 32, then divide by 1.8.
So 77-32=45, then divide that number by 1.8.
45 divided by 1.8 = 25 degrees Celsius.
Rock on!

C = 5/9 * (F-32)
The way to do this is by a linear equation. You know the boiling points at both F and C being 212 and 100 respectively. You know the freezing points to be 32 and 0 respectively. That gives a relationship between the two. Both are linear functions.
For every (212-32) degrees F there are (100-0) degrees C. That is about 100/180 or 5/9 degrees C for every 9/9 degrees F. By that you use that as a multiplier. 77-32=45 degrees difference from the know point. 45*5/9 = 25 degrees C. Add that to zero which is the reference for C. By this you get the formula:
C = 5/9 * (F-32)

Subtract 32 and multiply by 5/9.
