Explanation:
We need to fill in the missing numbers so that both sides of each equation are equal. Let’s go one by one and solve carefully.
1) ___ − 3 = 4 × 2
Right side: 4 × 2 = 8
So: ___ − 3 = 8 → ___ = 8 + 3 =
11
2) 4 × ___ = 10 − 6
Right side: 10 − 6 = 4
So: 4 × ___ = 4 → ___ = 4 ÷ 4 =
1
3) 6 × 3 = 7 + ___
Left: 6 × 3 = 18
So: 18 = 7 + ___ → ___ = 18 − 7 =
11
4) ___ + 7 = 3 × 3
Right: 3 × 3 = 9
So: ___ + 7 = 9 → ___ = 9 − 7 =
2
5) ___ − 5 = 2 × 7
Right: 2 × 7 = 14
So: ___ − 5 = 14 → ___ = 14 + 5 =
19
6) 8 × 4 = 40 − ___
Left: 8 × 4 = 32
So: 32 = 40 − ___ → ___ = 40 − 32 =
8
7) 5 × 4 = ___ + 3
Left: 5 × 4 = 20
So: 20 = ___ + 3 → ___ = 20 − 3 =
17
8) ___ − 5 = 8 × 2
Right: 8 × 2 = 16
So: ___ − 5 = 16 → ___ = 16 + 5 =
21
9) 15 − ___ = 12 − 9
Right: 12 − 9 = 3
So: 15 − ___ = 3 → ___ = 15 − 3 =
12
10) 7 × 3 = 30 − ___
Left: 7 × 3 = 21
So: 21 = 30 − ___ → ___ = 30 − 21 =
9
11) ___ + 4 = 15 − 8
Right: 15 − 8 = 7
So: ___ + 4 = 7 → ___ = 7 − 4 =
3
12) ___ × 6 = 12 × 2
Right: 12 × 2 = 24
So: ___ × 6 = 24 → ___ = 24 ÷ 6 =
4
13) 14 − ___ = 6 × 0
Right: 6 × 0 = 0
So: 14 − ___ = 0 → ___ = 14 − 0 =
14
14) 2 × 9 = ___ − 3
Left: 2 × 9 = 18
So: 18 = ___ − 3 → ___ = 18 + 3 =
21
15) ___ + 5 = 7 × 4
Right: 7 × 4 = 28
So: ___ + 5 = 28 → ___ = 28 − 5 =
23
16) 29 − ___ = 2 × 6
Right: 2 × 6 = 12
So: 29 − ___ = 12 → ___ = 29 − 12 =
17
17) 11 × 2 = 6 + ___
Left: 11 × 2 = 22
So: 22 = 6 + ___ → ___ = 22 − 6 =
16
18) 8 × ___ = 50 − 2
Right: 50 − 2 = 48
So: 8 × ___ = 48 → ___ = 48 ÷ 8 =
6
Let me double-check a few to be safe:
- #1: 11 − 3 = 8, 4 × 2 = 8
✔
- #13: 14 − 14 = 0, 6 × 0 = 0
✔
- #18: 8 × 6 = 48, 50 − 2 = 48
✔
All look correct.
Final Answer:
1) 11
2) 1
3) 11
4) 2
5) 19
6) 8
7) 17
8) 21
9) 12
10) 9
11) 3
12) 4
13) 14
14) 21
15) 23
16) 17
17) 16
18) 6
