\[
38 - 19 = 19
\]
- So, the answer is:
19
2.
5 × ____ = 60
- To find the missing number, divide 60 by 5:
\[
60 ÷ 5 = 12
\]
- So, the answer is:
12
3.
45 - ____ = 30
- To find the missing number, subtract 30 from 45:
\[
45 - 30 = 15
\]
- So, the answer is:
15
4.
36 ÷ ____ = 9
- To find the missing number, divide 36 by 9:
\[
36 ÷ 9 = 4
\]
- So, the answer is:
4
5.
26 + ____ = 52
- To find the missing number, subtract 26 from 52:
\[
52 - 26 = 26
\]
- So, the answer is:
26
6.
____ × 8 = 56
- To find the missing number, divide 56 by 8:
\[
56 ÷ 8 = 7
\]
- So, the answer is:
7
7.
____ - 20 = 60
- To find the missing number, add 20 to 60:
\[
60 + 20 = 80
\]
- So, the answer is:
80
8.
____ ÷ 12 = 4
- To find the missing number, multiply 4 by 12:
\[
4 × 12 = 48
\]
- So, the answer is:
48
9.
____ + 15 = 45
- To find the missing number, subtract 15 from 45:
\[
45 - 15 = 30
\]
- So, the answer is:
30
10.
____ × 6 = 24
- To find the missing number, divide 24 by 6:
\[
24 ÷ 6 = 4
\]
- So, the answer is:
4
Column 2:
1.
40 + ____ = 100
- To find the missing number, subtract 40 from 100:
\[
100 - 40 = 60
\]
- So, the answer is:
60
2.
7 × ____ = 49
- To find the missing number, divide 49 by 7:
\[
49 ÷ 7 = 7
\]
- So, the answer is:
7
3.
22 - ____ = 8
- To find the missing number, subtract 8 from 22:
\[
22 - 8 = 14
\]
- So, the answer is:
14
4.
54 ÷ ____ = 9
- To find the missing number, divide 54 by 9:
\[
54 ÷ 9 = 6
\]
- So, the answer is:
6
5.
52 + ____ = 64
- To find the missing number, subtract 52 from 64:
\[
64 - 52 = 12
\]
- So, the answer is:
12
6.
____ × 7 = 21
- To find the missing number, divide 21 by 7:
\[
21 ÷ 7 = 3
\]
- So, the answer is:
3
7.
____ - 50 = 50
- To find the missing number, add 50 to 50:
\[
50 + 50 = 100
\]
- So, the answer is:
100
8.
____ ÷ 6 = 6
- To find the missing number, multiply 6 by 6:
\[
6 × 6 = 36
\]
- So, the answer is:
36
9.
____ + 60 = 70
- To find the missing number, subtract 60 from 70:
\[
70 - 60 = 10
\]
- So, the answer is:
10
10.
____ × 12 = 36
- To find the missing number, divide 36 by 12:
\[
36 ÷ 12 = 3
\]
- So, the answer is:
3
Final Answers:
- Column 1:
19, 12, 15, 4, 26, 7, 80, 48, 30, 4
- Column 2:
60, 7, 14, 6, 12, 3, 100, 36, 10, 3
\boxed{19, 12, 15, 4, 26, 7, 80, 48, 30, 4, 60, 7, 14, 6, 12, 3, 100, 36, 10, 3}
