How do you convert 45°C to Fahrenheit?

Recall the formula to convert this.
##mathbf(T_C = 5/9(T_F – 32))##
Of course, ##T_C## is the temperature in ##””^@ “C”##, and ##T_F## is the temperature in ##””^@ “F”##.
Let’s test this to make sure. I know that ##100^@ “C” = 212^@ “F”## is the boiling point of water, so let’s see if that works.
##color(green)(T_C) = 5/9(212 – 32)##
##= 5/9(180)##
##= 5*20 = color(green)(100^@ “C”)##
Yep. Now use it on ##45^@ “C”##.
##45 = 5/9(T_F – 32)##
##405/5 = T_F – 32##
##81 + 32 = color(blue)(113^@ “F” = T_F)##
