A warm day has a high temperature of 38.0°C. What is this temperature in degrees Fahrenheit?
The temperature is ##"100.4 °F"##.
The formula is
##"F" = 9/5"C + 32"##
Hence,
##"F" =9/5×38.0 + 32 = 100.4##
The above formula ignores units. Here it is with units.
##"F" = 38.0 color(red)(cancel(color(black)("°C"))) × "9 °F"/(5 color(red)(cancel(color(black)("°C")))) + "32 °F" = "68.4 °F + 32 °F" = "100.4 °F"##
The temperature is ##"100.4 °F"##.
