Answer: Q is incorrect.
Explanation:
P = -24/3
(P = 24 divided by 3 which is 8, so P= -8)
Q = -9/2
(Q = 9 divided by 2 which is 4.5, Q= -4.5)
R= 7/2
(R= 7 divided by 2 which is 3.5, Q= 3.5)
S= 15/3
(S= 15 divided by 3 (= 5), so S= 5)
So... Looking at the number line, Q is actually on the point -3.5 instead of where it should be, -4.5. It is easy to miss at first glance but it counts backwards into the negative numbers.
Therefore point Q is not correctly placed on the number line.
I hope this helps :)
