## Homework Statement

the fahrenheit temp scale is defined to that ice melts at 32 F and water boils at 212 F. Derive formulas for converting fahrenheit to celsius and back.

## Homework Equations

c=5/9(f-32)

## The Attempt at a Solution

ok so i figured that 212-32= 180

and

100-0=100

so the ratio of c/f= 5/9

i don't know how to get the 32 part into the equation
