Explanation:
1. question one is asking you to name the opposite of each number, positive/negative, so:
a. the opposite of 5 = -5
b. the opposite of 28 = -28
c. the opposite of -10.4 = 10.4
d. the opposite of 0.875 = -0.875
e. the opposite of 0 = 0
f. the opposite of -8,003 = 8,003
2. question two is asking you to plot the numbers on the number line, so:
-1.5 goes in between the -2 and -1
3/2 = 1.5, so it goes in between the positive 2 and positive 1
-4/3 = -1.33333.., so it goes in between the -1.5 and -1
-3/2 = -1.5, so it goes in the same place, in between the -2 and -1
3. question 3 is asking you to plot the numbers on the number line, so:
1.5 = 1.5 (goes between the positive 1 and positive 2)
the opposite of -2 = 2
the opposite of 0.5 = -0.5 (goes between 0 and -1)
-2 = -2
I hope this helps!!
