Answer 1

Answer:

Explanation:

- 40 DEGREE CELCIUS.

IN FACT FAHRENHEIT AND DEGREE CELCIUS SCALES HAVE THE SAME VALUE FOR - 40.

YOU CAN VERIFY IT BY USING THE FORMULA---> C/5 = (F-32)/9 WHERE C= CELCIUS SCALE VALUE AND F IS FAHRENHEIT SCALE VALUE.

SO C/5 = ( -40-32)/9= -72/9= -8

=> C/5= -8

=> C= -40 DEGREE CELCIUS.
