11
2. 7 × ___ = 28
→ Divide 28 by 7: 28 ÷ 7 =
4
3. 90 - ___ = 50
→ Subtract 50 from 90: 90 - 50 =
40
4. 24 + ___ = 48
→ 48 - 24 =
24
5. 11 × ___ = 77
→ 77 11 =
7
6. ___ - 10 = 25
→ Add 10 to 25: 25 + 10 =
35
7. ___ + 44 = 64
→ 64 - 44 =
20
8. ___ × 5 = 20
→ 20 ÷ 5 =
4
9. ___ - 10 = 35
→ 35 + 10 =
45
10. ___ + 40 = 80
→ 80 - 40 =
40

11. 22 + ___ = 38
→ 38 - 22 =
16
12. 6 × ___ = 36
→ 36 ÷ 6 =
6
13. 35 - ___ = 20
→ 35 - 20 =
15
14. 30 + ___ = 60
→ 60 - 30 =
30
15. 4 × ___ = 8
→ 8 ÷ 4 =
2
16. ___ - 9 = 18
→ 18 + 9 =
27
17. ___ + 17 = 30
→ 30 - 17 =
13
18. ___ × 12 = 24
→ 24 ÷ 12 =
2
19. ___ - 20 = 20
→ 20 + 20 =
40
