Math worksheet for calculating the average of three numbers with a fun panda theme.

To solve the problem of finding the average of each set of three numbers, we need to follow these steps:

Steps to Find the Average:

1. Add the three numbers in each set.
2. Divide the sum by 3 (since there are three numbers).
3. Repeat this process for each set of numbers.

Let's go through each set step by step.

---

Set 1: \(8, 7, 9\)

1. Add the numbers:
\[
8 + 7 + 9 = 24
\]
2. Divide the sum by 3:
\[
\frac{24}{3} = 8
\]

Average: \(8\)

---

Set 2: \(7, 9, 10\)

1. Add the numbers:
\[
7 + 9 + 10 = 26
\]
2. Divide the sum by 3:
\[
\frac{26}{3} \approx 8.67
\]

Average: \(8.67\)

---

Set 3: \(10, 29, 30\)

1. Add the numbers:
\[
10 + 29 + 30 = 69
\]
2. Divide the sum by 3:
\[
\frac{69}{3} = 23
\]

Average: \(23\)

---

Set 4: \(3, 10, 17\)

1. Add the numbers:
\[
3 + 10 + 17 = 30
\]
2. Divide the sum by 3:
\[
\frac{30}{3} = 10
\]

Average: \(10\)

---

Set 5: \(8, 7, 6\)

1. Add the numbers:
\[
8 + 7 + 6 = 21
\]
2. Divide the sum by 3:
\[
\frac{21}{3} = 7
\]

Average: \(7\)

---

Set 6: \(12, 20, 1\)

1. Add the numbers:
\[
12 + 20 + 1 = 33
\]

\]

Average: \(10\)

---

Set 8: \(15, 20, 25\)

1. Add the numbers:
\[
15 + 20 + 25 = 60

\frac{60}{3} = 20
\]

Average: \(20\)

---

Set 9: \(18, 12, 6\)

1. Add the numbers:
\[
18 + 12 + 6 = 36
\]

\[
\frac{36}{3} = 12
\]

Average: \(12\)

---

Set 10: \(14, 6, 16\)

1. Add the numbers:
\[
14 + 6 + 16 = 36
\]
2. Divide the sum by 3:
\[
\frac{36}{3} = 12
\]

Average: \(12\)

---

Set 11: \(15, 15, 12\)

1. Add the numbers:
\[
15 + 15 + 12 = 42
\]
2. Divide the sum by 3:
\[
\frac{42}{3} = 14
\]

Average: \(14\)

---

Set 12: \(2, 1, 22\)

1. Add the numbers:
\[
2 + 1 + 22 = 25
\]
2. Divide the sum by 3:
\[
\frac{25}{3} \approx 8.33
\]

Average: \(8.33\)

---

Set 13: \(12, 18, 30\)

1. Add the numbers:
\[
12 + 18 + 30 = 60
\]
2. Divide the sum by 3:
\[
\frac{60}{3} = 20
\]

Average: \(20\)

---

Set 14: \(20, 30, 40\)

1. Add the numbers:
\[
20 + 30 + 40 = 90
\]
2. Divide the sum by 3:
\[
\frac{90}{3} = 30
\]

Average: \(30\)

---

Set 15: \(16, 22, 22\)

1. Add the numbers:
\[
16 + 22 + 22 = 60
