the formula C=5/9(F32) is used to convert Fahrenheit temperature,F, to Celsius temperature,C. What temperature in Fahrenheit is equivalent to a temperature of 100 Celsius.
I know that in Fahrenheit its 212 degrees, but i used it by using guess and check. i need help with how to use the formula.

To use the formula, plug in 100 for C and solve the resulting equation for F.
100 = (5/9)(F32)
Multiply both sides by 9/5, and you get
180 = F  32
Now add 32 to both sides.
