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

#color(green)(T_C) = 5/9(212 - 32)#

#= 5/9(180)#

#= 5*20 = color(green)(100^@ "C")#

Yep. Now use it on

#45 = 5/9(T_F - 32)#

#405/5 = T_F - 32#

#81 + 32 = color(blue)(113^@ "F" = T_F)#
