Answer:
1)-22
2)-8
3)-1
Step-by-step explanation:
Subtract 15 from 7 to get - 8.
Sort (-8,-9-13,-2/5-3/5)
Subtract 13 from-9 to get - 22.
Sort(-8,-22,-2/5-3/5)
Since - 2/5=-0.4 and 3/5=0.6
Sort((-8,22,-23)
5
Subtract 3 from - 2 to get - 5.
Sort(-8,-22,-5/5)
Divide - 5 by 5 to get +=1.
Sort(-8,-22,-1)
-8.-8
-22,-8 insert - 1
=22,-8,-1
