Answer:
-9 x -3
Step-by-step explanation:
-7 x -2 will give +14.
-9 x -3 will give +27
+27 is greater than +14.
Two negative numbers multiplied will give a positive answer. (Always)
You divide 18 by 90 and get .2 then multiply it by 100 and get 20. Then you subtract 20 from 100 and get 80. You got 80% correct.
