Question

To convert a temperature in degrees Celsius to degrees Fahrenheit multiply the Celsius temperature by 9/5 and then add 32 F Is a temperature in degrees Celsius proportional to its equivalent temperature in degrees Fahrenheit.

Answer 1

no, the adding/subtracting of the constant 32 "wrecks" the proportional property,
that is, we cannot set it up as a ratio of the form
a/b = c/d

Answer 2
