Standard form means to convert a rational number into is simplest form so that there is no common factor between the numerator and denominator , other than one.

-24/40. It's greatest common factor is 8 so we will divide 8 from the numerator and denominator.

(-24÷8)/(40÷8)= -3/5

harshitayadav65: I am sorry for disturbing you again and again if you are getting disturbed
sohailanjum2018: every hour 5 degree Celsius decrease.so after 8 hours degree Celsius decrease is = 8*5 =40 degree decrease so room temp is 32-40 = -8 degree Celsius
