The problem is 11 ⁰F = ?⁰C

1.) determine the freezing point of the original temperature to get the real degree number.

Fahrenheit freezing point = 32

11 - 32 = -27

2.) Use the F to C conversion factor: 5 ⁰C/9 ⁰F.

27 ⁰F (5 ⁰C/9 ⁰F) = -14.9999

Rounding to nearest degree: -15⁰C.

But textbook answer was -12 ⁰C

Can anyone suggest where I have made a mistake here?

11 - 32 = -27

F like fail.

11 - 32 = -27

F like fail.

Yes, I realized that later. Simple arithmetic mistakes are my most common problem.
