Question

the temperature on a summer day is 77 degree fahrenheit , the formula convert temperature to degrees Celsius =5/9 (f-32). what is the corresponding temperature in degrees celcius?

Answer 1

$C=\frac{5}{9}(F-32)\\\\F=77\\\\put\ value\ of\ F\ to\ equation:\\\\C=\frac{5}{9}(77-32)=\frac{5}{9}\cdot45=5\cdot5=25\\\\\boxed{77^o F=25^o C}$
