Explanation:
We are given six problems. Each problem says how many *tens* and how many *ones* to add.
Our job is to:
1. Write the expanded form (that means write the value of the tens and ones as numbers),
2. Then find the total.
Remember:
- 1 ten = 10
- 2 tens = 20
- 3 tens = 30
- etc.
- 1 one = 1
- 2 ones = 2
- etc.
Let’s do each one step by step:
1.
1 ten + 4 ones
→ 1 ten = 10
→ 4 ones = 4
Expanded:
10 + 4
Total: 10 + 4 =
14
2.
3 tens + 8 ones
→ 3 tens = 30
→ 8 ones = 8
Expanded:
30 + 8
Total: 30 + 8 =
38
3.
2 tens + 7 ones
→ 2 tens = 20
→ 7 ones = 7
Expanded:
20 + 7
Total: 20 + 7 =
27
4.
1 ten + 9 ones
→ 1 ten = 10
→ 9 ones = 9
Expanded:
10 + 9
Total: 10 + 9 =
19
5.
4 tens + 2 ones
→ 4 tens = 40
→ 2 ones = 2
Expanded:
40 + 2
Total: 40 + 2 =
42
6.
5 tens + 3 ones
→ 5 tens = 50
→ 3 ones = 3
Expanded:
50 + 3
Total: 50 + 3 =
53
Let me double-check all totals:
- 10 + 4 = 14
✔
- 30 + 8 = 38
✔
- 20 + 7 = 27
✔
- 10 + 9 = 19
✔
- 40 + 2 = 42
✔
- 50 + 3 = 53
✔
All correct.
Final Answer:
10 + 4 = 14
30 + 8 = 38
20 + 7 = 27
10 + 9 = 19
40 + 2 = 42
50 + 3 = 53
