4) 10.7 – 0.35 ? 8.55 – 0.1
Left: 10.70 – 0.35 =
10.35
Right: 8.55 – 0.10 =
8.45

→
>
---
5) 3.8 ? 5.8 – 1.2
Right side: 5.8 – 1.2 =
4.6
Compare: 3.8 vs 4.6 → 3.8 is less.
→
<

6) 4.608 – 2.9 ? 1.7
Left: 4.608 – 2.900 =
1.708
Compare: 1.708 vs 1.7 → 1.708 is greater.
→
>
*(Note: 1.7 is same as 1.700)*

7) 2.75 ? 0.9 + 0.85
Right: 0.90 + 0.85 =
1.75
Compare: 2.75 vs 1.75 → 2.75 is greater.
→
>
---
8) 128.04 ? 126 + 1.2 + 0.84
Right: 126 + 1.2 = 127.2; 127.2 + 0.84 =
