Question

If the temperature is 65°F outside, what is the temperature in degrees Celsius?

Answer 1

`"18.33°C"`

Explanation:

Temperature in Celsius (`"C"`) and Fahrenheit (`"F"`) are related as

`color(blue)("C"/5 = "F – 32"/9)`

`"C" = 5 × "F – 32"/9`

`"C" = 5 × (65 - 32)/9`

`"C" = 5 × 33/9 = 55/3 = "18.33 degrees"`
