Two hundred fifty-five and three tenths as a decimal is 255.3
The answer for your question is (1/2) and alternate form is 0.5 and 2^-1
6 degrees below zero is the same thing as -6 so the answer is B. The high temperature is irrelevant to the finding the integer of the low temperature.
Number 1 & 2 both goes in 200. Numbers 9,3, & 27 goes into 81. Numbers 10,5,4,8,20, & 25 goes into 200. Hope this helps
