The folrmula F=9/5c+32 can be used to make temperature conversions with the Celsius ans Fahrenheit temperature scales.

F-Fahrenheit temperature

C=Celsius temperature

Convert 100 degress Fahrenheit to the Celsius temperature scale.

Book says answer is 37.78 Celsius

I am not arriving at this answer.

Substitute the 100 degrees F

100=9/5C+32

subtract 32 from each side

100-32=9/5C

68=9/5C

68x5/9=C

so

C=37.8

Is this OK. Can you see where you went wrong?

Using your equation F = (9/5) C + 32, which IS the correct equation,

100 = (9/5) C + 32

(9/5) C = 68

C = (5/9)*68 = 37.78 (or 37 7/9)
