Answer:

-0.7
Step-by-step explanation:
Both
and -0.7 are negative so therefore, 1 is the greatest
is -0.6 which is greater than -0.7 so it's the 2nd greatest
and -0.7 is the least
Because it's decreasing, you use the formula (1-x/100)y with x the percentage decreased which is here 40, and y the number decreased which is here 90
So we get
(1-40/100) * 90
(100/100 - 40/100) * 90
60/100 * 90
5400/100
54
So 90 decreased by 40% is 54
