Let’s solve each problem step by step using the given values:
h = 10,
j = 7, and
k = 4
---
1. 30 ÷ h
Replace h with 10 → 30 ÷ 10 =
3
2. j × 11
Replace j with 7 → 7 × 11 =
77
3. k × j
Replace k with 4, j with 7 → 4 × 7 =
28
4. k + j
Replace k with 4, j with 7 → 4 + 7 =
11
5. 3 + k
Replace k with 4 → 3 + 4 =
7
6. h × k
Replace h with 10, k with 4 → 10 × 4 =
40
7. 9 × (j + 5)
First, do what’s inside the parentheses: j + 5 = 7 + 5 = 12
Then multiply: 9 × 12 =
108
8. 21 ÷ (k – 1)
First, do what’s inside the parentheses: k – 1 = 4 – 1 = 3
Then divide: 21 ÷ 3 =
7

Final Answer:
1. 3
2. 77
3. 28
4. 11
5. 7
6. 40
7. 108
8. 7
