Let’s solve each problem one by one. Remember, we’re looking for the missing number that makes the addition true. To find it, subtract the first number from the total.
---
1) 41 + ___ = 69 → 69 - 41 =
28
2) 70 + ___ = 72 → 72 - 70 =
2
3) 22 + ___ = 62 → 62 - 22 =
40
4) 27 + ___ = 35 → 35 - 27 =
8
5) 09 + ___ = 31 → 31 - 9 =
22
6) 30 + ___ = 64 → 64 - 30 =
34
7) 00 + ___ = 19 → 19 - 0 =
19
8) 35 + ___ = 63 → 63 - 35 =
28
9) 17 + ___ = 23 → 23 - 17 =
6
10) 22 + ___ = 46 → 46 - 22 =
24
Now the second column:
11) 10 + ___ = 13 → 13 - 10 =
3
12) 50 + ___ = 24 → Wait! This can’t be right — you can’t add a positive number to 50 and get 24. But since this is Grade 4, maybe it’s a typo? Let’s check: 50 + ? = 24 → ? = 24 - 50 =
-26. That’s negative — probably not intended. Maybe it’s supposed to be 50 + ___ = 74? Or 24 + ___ = 50? But as written, mathematically, it’s
-26. We’ll go with what’s written.
But let’s double-check all others first.
13) 00 + ___ = 35 → 35 - 0 =
35
14) 48 + ___ = 49 → 49 - 48 =
1
15) 52 + ___ = 58 → 58 - 52 =
6
16) 29 + ___ = 29 → 29 - 29 =
0
17) 30 + ___ = 51 → 51 - 30 =
21
18) 70 + ___ = 84 → 84 - 70 =
14
19) 21 + ___ = 27 → 27 - 21 =
6
20) 52 + ___ = 80 → 80 - 52 =
28
Back to #12: 50 + ___ = 24. If we follow math strictly, answer is -26. But in Grade 4, they usually don’t do negatives yet. It might be a mistake in the worksheet. However, since we must solve as given, we’ll put
-26, but note: if your teacher expects only positive numbers, ask them about this one.
Actually — wait! Looking again at #12: “50 + ___ = 24” — that’s impossible with positive whole numbers. Maybe it’s meant to be “___ + 50 = 24”? Still same thing. Or perhaps it’s “50 - ___ = 24”? Then it would be 26. But the sign is clearly “+”.
Given the context of an elementary worksheet, it’s likely a typo. But since we have to answer based on what’s written, we’ll calculate it correctly as per math rules.
So final answers:
Final Answer:
1) 28
2) 2
3) 40
4) 8
5) 22
6) 34
7) 19
8) 28
9) 6
10) 24
11) 3
12) -26 *(Note: This may be a typo — check with your teacher)*
13) 35
14) 1
15) 6
16) 0
17) 21
18) 14
19) 6
20) 28
