Explanation:
This is a multiplication tables test. Each problem has one missing number — either the multiplier or the multiplicand — and you need to find it using division, because:
If
a × b = c, then:
- To find
a, do
c ÷ b
- To find
b, do
c ÷ a
Let’s solve each one step by step (I’ll group them for speed but check every answer carefully):
1) 2 × ___ = 10 → 10 ÷ 2 =
5
2) ___ × 3 = 3 → 3 ÷ 3 =
1
3) ___ × 5 = 15 → 15 ÷ 5 =
3
4) 10 × ___ = 50 → 50 ÷ 10 =
5
5) 4 × ___ = 8 → 8 ÷ 4 =
2
6) ___ × 10 = 0 → 0 ÷ 10 =
0
7) ___ × 5 = 25 → 25 ÷ 5 =
5
8) 2 × ___ = 14 → 14 ÷ 2 =
7
9) ___ × 4 = 16 → 16 ÷ 4 =
4
10) ___ × 10 = 30 → 30 ÷ 10 =
3
11) 3 × ___ = 18 → 18 ÷ 3 =
6
12) 5 × ___ = 5 → 5 ÷ 5 =
1
13) ___ × 2 = 4 → 4 ÷ 2 =
2
14) ___ × 3 = 12 → 12 ÷ 3 =
4
15) 4 × ___ = 20 → 20 ÷ 4 =
5
16) 10 × ___ = 70 → 70 ÷ 10 =
7
17) ___ × 5 = 20 → 20 ÷ 5 =
4
18) ___ × 3 = 0 → 0 ÷ 3 =
0
19) 2 × ___ = 20 → 20 ÷ 2 =
10
20) ___ × 5 = 35 → 35 ÷ 5 =
7
21) ___ × 4 = 24 → 24 ÷ 4 =
6
22) 2 × ___ = 16 → 16 ÷ 2 =
8
23) ___ × 10 = 80 → 80 ÷ 10 =
8
24) ___ × 3 = 21 → 21 ÷ 3 =
7
25) 5 × ___ = 10 → 10 ÷ 5 =
2
26) ___ × 2 = 14 → 14 ÷ 2 =
7
27) 3 × ___ = 27 → 27 ÷ 3 =
9
28) 10 × ___ = 100 → 100 ÷ 10 =
10
29) ___ × 4 = 32 → 32 ÷ 4 =
8
30) 2 × ___ = 18 → 18 ÷ 2 =
9
31) ___ × 3 = 6 → 6 ÷ 3 =
2
32) ___ × 4 = 28 → 28 ÷ 4 =
7
33) 5 × ___ = 45 → 45 ÷ 5 =
9
34) 3 × ___ = 24 → 24 ÷ 3 =
8
35) ___ × 10 = 80 → 80 ÷ 10 =
8
36) ___ × 5 = 35 → 35 ÷ 5 =
7
37) 4 × ___ = 36 → 36 ÷ 4 =
9
38) 3 × ___ = 12 → 12 ÷ 3 =
4
39) ___ × 5 = 50 → 50 ÷ 5 =
10
40) ___ × 2 = 18 → 18 ÷ 2 =
9
Let me double-check a few tricky ones:
- #6: anything × 10 = 0 → only 0 works
✔
- #18: ___ × 3 = 0 → only 0 works
✔
- #28: 10 × 10 = 100
✔
- #35: 8 × 10 = 80
✔
- #39: 10 × 5 = 50
✔
All correct.
Final Answer:
5, 1, 3, 5, 2, 0, 5, 7, 4, 3, 6, 1, 2, 4, 5, 7, 4, 0, 10, 7, 6, 8, 8, 7, 2, 7, 9, 10, 8, 9, 2, 7, 9, 8, 8, 7, 9, 4, 10, 9
