1) Already done:
4 × 3 = 12
2 + 9 = 11
→ 12 > 11 →

2)
30 - 17 = 13
2 × 7 = 14
→ 13 < 14 →

3)
½ of 30 = 15
5 × 3 = 15
→ 15 = 15 →

4)
30 × 4 = 120
200 - 50 = 150
→ 120 < 150 →

5)
5 × 9 = 45
17 + 27 = 44
→ 45 > 44 →

6)
18 ÷ 6 = 3
21 - 19 = 2
→ 3 > 2 →
>

7)
3 × 9 = 27
100 - 72 = 28
→ 27 < 28 →

12)
28 ÷ 4 = 7
½ of 14 = 7
→ 7 = 7 →

13)
40 × 3 = 120
200 - 80 = 120
→ 120 = 120 →
