It looks like you've uploaded a worksheet titled "Cross out the equations that are false", containing a grid of multiplication problems. The task is to identify which multiplication equations are false (incorrect) and cross them out.
Let’s go through each equation systematically and determine whether it's correct or not.

List of incorrect equations:
1. 6 × 12 = 91 → should be 72
2. 9 × 3 = 24 → should be 27
3. 9 × 2 = 30 → should be 18
4. 8 × 11 = 99 → should be 88
5. 5 × 7 = 51 → should be 35
6. 7 × 7 = 63 → should be 49
7. 4 × 3 = 8 → should be 12
8. 6 × 3 = 21 → should be 18
9. 10 × 7 = 77 → should be 70
10. 3 × 8 = 27 → should be 24
11. 10 × 7 = 74 → should be 70
12. 8 × 5 = 48 → should be 40
13. 3 × 6 = 60 → should be 18
14. 12 × 8 = 88 → should be 96
15. 7 × 2 = 32 → should be 14
16. 12 × 3 = 38 → should be 36
17. 4 × 6 = 24 → but listed as 20 → ✘
18. 2 × 9 = 20 → should be 18
19. 7 × 11 = 68 → should be 77
20. 7 × 3 = 35 → should be 21
21. 4 × 8 = 88 → should be 32
22. 12 × 2 = 36 → should be 24
23. 12 × 3 = 110 → should be 36
24. 10 × 9 = 99 → should be 90
25. 4 × 4 = 15 → should be 16
Wait — let's count carefully.
From earlier list, we had:
- 4 × 6 = 20 → ✘ (should be 24)
- 4 × 4 = 15 → ✘ (should be 16)
So total incorrect ones: Let's recount all the ✘ entries.
From above, we have 25 incorrect equations.
But wait — double-checking:
Let me list all the false ones clearly:
1. 6 × 12 = 91 ✘
2. 9 × 3 = 24 ✘
3. 9 × 2 = 30 ✘
4. 8 × 11 = 99 ✘
5. 5 × 7 = 51 ✘
6. 7 × 7 = 63 ✘
7. 4 × 3 = 8 ✘
8. 6 × 3 = 21 ✘
9. 10 × 7 = 77 ✘
10. 3 × 8 = 27 ✘
11. 10 × 7 = 74 ✘
12. 8 × 5 = 48 ✘
13. 3 × 6 = 60 ✘
14. 12 × 8 = 88 ✘
15. 7 × 2 = 32 ✘
16. 12 × 3 = 38 ✘
17. 4 × 6 = 20 ✘
18. 2 × 9 = 20 ✘
19. 7 × 11 = 68 ✘
20. 7 × 3 = 35 ✘
21. 4 × 8 = 88 ✘
22. 12 × 2 = 36 ✘
23. 12 × 3 = 110 ✘
24. 10 × 9 = 99 ✘
25. 4 × 4 = 15 ✘
✔ That’s 25 false equations.
Now, total equations: 63
So number of correct equations: 63 - 25 = 38
But the bottom says: "63 problems — wrong — correct"
So you would fill in:
- Wrong: 25
- Correct: 38
