Let's solve the worksheet step by step. The task is to build a 5-digit number from its parts — that is, we are given the expanded form of a number (in terms of place values), and we need to write the full 5-digit number.

🔢 Understanding Place Values:


A 5-digit number has the following place values:

- Ten Thousands (10,000)
- Thousands (1,000)
- Hundreds (100)
- Tens (10)
- Ones (1)

We’ll add up all the parts to get the full number.

1.
40,000 + 2,000 + 400 + 80 + 8
= 40,000 + 2,000 = 42,000
+ 400 = 42,400
+ 80 = 42,480
+ 8 = 42,488

Answer: 42,488

2.
70,000 + 5,000 + 200 + 30 + 5
= 70,000 + 5,000 = 75,000
+ 200 = 75,200
+ 30 = 75,230
+ 5 = 75,235

Answer: 75,235

3.
40,000 + 5,000 + 500 + 80
= 40,000 + 5,000 = 45,000
+ 500 = 45,500
+ 80 = 45,580

Answer: 45,580

4.
90,000 + 1,000 + 400 + 80 + 3
= 90,000 + 1,000 = 91,000
+ 400 = 91,400
+ 80 = 91,480
+ 3 = 91,483

Answer: 91,483

5.
10,000 + 2,000 + 800 + 30 + 7
= 10,000 + 2,000 = 12,000
+ 800 = 12,800
+ 30 = 12,830
+ 7 = 12,837

Answer: 12,837

6.
10,000 + 8,000 + 400 + 10 + 4
= 10,000 + 8,000 = 18,000
+ 400 = 18,400
+ 10 = 18,410
+ 4 = 18,414

Answer: 18,414

7.
10,000 + 9,000 + 400 + 40 + 3
= 10,000 + 9,000 = 19,000
+ 400 = 19,400
+ 40 = 19,440
+ 3 = 19,443

Answer: 19,443

8.
70,000 + 3,000 + 900 + 70 + 1
= 70,000 + 3,000 = 73,000
+ 900 = 73,900
+ 70 = 73,970
+ 1 = 73,971

Answer: 73,971

9.
20,000 + 2,000 + 400 + 20 + 3
= 20,000 + 2,000 = 22,000
+ 400 = 22,400
+ 20 = 22,420
+ 3 = 22,423

Answer: 22,423

📌 Explanation:


Each number is built by adding the values based on their place value:
- Ten thousands → 10,000s
- Thousands → 1,000s
- Hundreds → 100s
- Tens → 10s
- Ones → 1s

You simply add all the parts together to get the complete 5-digit number.
