Question

What is 80 degrees Celsius in Fahrenheit?

Answer 1

`80^@` Celsius `= 112^@` Fahrenheit

Explanation:

Helpful tings to remember:
#{: (,color(white)("XXX"),"degrees C",color(white)("XXX"),"degrees F"), ("freezing point of water",color(white)("XXX"),100,color(white)("XXX"),212), ("freezing point of water",color(white)("XXX"),0,color(white)("XXX"),32) :}#

From this it follows that `100C^@ = 180F^@`

`80^@C` is `80C^@` above freezing
`color(white)("XXX")= 180/100*80 F^@ = 144F^@` above freezing

`144F^@` above freezing is
`color(white)("XXX") 144-32 = 112 ^@F`
