Obviously 0, 1/4 and 1/2 are bigger than the previous 2 numbers. We start with -19 because that is the smallest number there is in this group. The next one we go with is -8. We chose these two because they are negative. 0, 1/4 and 1/2 are next. 1/4=0.25 1/2=0.5
So the answer would be -19, -8, 0, 1/4, 1/2
