Answer:
-3 1/2 > -4.5
Step-by-step explanation:
1.5 > 2 1/2 False
1/2 > 0.5 False
-2.5 > -1.5 False
-3 1/2 > -4.5 True
1.5 > 2 1/2
1/2 = 0.5
2 + 0.5 = 2.5
1.5 is not > 2.5
1.5 < 2.5
1/2 > 0.5
1/2 = 0.5
0.5 is not > 0.5
0.5 = 0.5
-2.5 > -1.5
Negative numbers are oposite of positive numbers when using inequalities. Just as 0 < 1, -1 < 0.
-2.5 is not > -1.5
-2.5 < -1.5
-3 1/2 > -4.5
1/2 = 0.5
3 + 0.5 = 3.5
-3.5 > -4.5
Answer:
