You can convert temperature given in degrees celsius to a fahrenheit temperature by using the expression 9x / 5 32 , where x is the celsius temperature .
a. water freezes when the temperature is 0 degree
c. at what fahrenheit temperature does water freeze ?
b. water boils at 100 degree celsius . at what temperature does water boil in degrees fahrenheit ?
c. the temperature of some water is 15 degree celsius . what is the fahrenheit temperature ?

The formula looks better this way:
Fahrenheit = (9/5 * Celsius) +32

a. water freezes when the temperature is 0 degree CELSIUS
At what Fahrenheit temperature does water freeze ?
Fahrenheit = (9/5 * 0) +32
Fahrenheit = 32

b.water boils at 100 degree Celsius.
At what temperature does water boil in degrees Fahrenheit ?
Fahrenheit = (9/5 * Celsius) +32
Fahrenheit = (9/5 * 100) + 32
Fahrenheit = 180 + 32
Fahrenheit = 212

c. the temperature of some water is 15 degree Celsius . what is the Fahrenheit temperature ?

Fahrenheit = (9/5 * Celsius) + 32
Fahrenheit = (9/5 * 15) + 32
Fahrenheit = 27 + 32
Fahrenheit = 59
