Let’s solve each fact family step by step.
A “fact family” uses three numbers to make two multiplication and two division facts.
The triangle shows the three numbers: the top number is the product (for multiplication) or dividend (for division), and the bottom two are the factors or divisor/quotient.
We’ll go one by one.

Problem 1: Triangle has 9, 1, 9
→ Multiplication:
1 × 9 = 9
9 × 1 = 9
→ Division:
9 ÷ 1 = 9
9 ÷ 9 = 1
✔ Check: All use only 1, 9, 9 — correct.
---
Problem 2: Triangle has 60, 6, 10
→ Multiplication:
6 × 10 = 60
10 × 6 = 60
→ Division:
60 ÷ 6 = 10
60 ÷ 10 = 6
✔ Check: 6×10=60, 60÷6=10 — all good.
---
Problem 3: Triangle has 27, 9, 3
→ Multiplication:
9 × 3 = 27
3 × 9 = 27
→ Division:
27 ÷ 9 = 3
27 ÷ 3 = 9
✔ Check: 9×3=27, 27÷3=9 — perfect.
---
Problem 4: Triangle has 14, 7, 2
→ Multiplication:
7 × 2 = 14
2 × 7 = 14
→ Division:
14 ÷ 7 = 2
14 ÷ 2 = 7
✔ Check: 7×2=14, 14÷2=7 — yes.
---
Problem 5: Triangle has 28, 4, 7
→ Multiplication:
4 × 7 = 28
7 × 4 = 28
→ Division:
28 ÷ 4 = 7
28 ÷ 7 = 4
✔ Check: 4×7=28, 28÷7=4 — correct.
---
Problem 6: Triangle has 21, 7, 3
→ Multiplication:
7 × 3 = 21
3 × 7 = 21
→ Division:
21 ÷ 7 = 3
21 ÷ 3 = 7
✔ Check: 7×3=21, 21÷3=7 — good.
---
Problem 7: Triangle has 20, 5, 4
→ Multiplication:
5 × 4 = 20
4 × 5 = 20
→ Division:
20 ÷ 5 = 4
20 ÷ 4 = 5
✔ Check: 5×4=20, 20÷4=5 — right.
---
Problem 8: Triangle has 80, 8, 10
→ Multiplication:
8 × 10 = 80
10 × 8 = 80
→ Division:
80 ÷ 8 = 10
80 ÷ 10 = 8
✔ Check: 8×10=80, 80÷10=8 — correct.
---
Problem 9: Triangle has 7, 1, 7
→ Multiplication:
1 × 7 = 7
7 × 1 = 7
→ Division:
7 ÷ 1 = 7
7 ÷ 7 = 1
✔ Check: Same as Problem 1 — makes sense.

Final Answer:
1.
1 × 9 = 9
9 × 1 = 9
9 ÷ 1 = 9
9 ÷ 9 = 1
2.
6 × 10 = 60
10 × 6 = 60
60 ÷ 6 = 10
60 ÷ 10 = 6
3.
9 × 3 = 27
3 × 9 = 27
27 ÷ 9 = 3
27 ÷ 3 = 9
4.
7 × 2 = 14
2 × 7 = 14
14 ÷ 7 = 2
14 ÷ 2 = 7
5.
4 × 7 = 28
7 × 4 = 28
28 ÷ 4 = 7
28 ÷ 7 = 4
6.
7 × 3 = 21
3 × 7 = 21
21 ÷ 7 = 3
21 ÷ 3 = 7
7.
5 × 4 = 20
4 × 5 = 20
20 ÷ 5 = 4
20 ÷ 4 = 5
8.
8 × 10 = 80
10 × 8 = 80
80 ÷ 8 = 10
80 ÷ 10 = 8
9.
1 × 7 = 7
7 × 1 = 7
7 ÷ 1 = 7
7 ÷ 7 = 1
