Let's solve each problem by adding the numbers together to write them in
standard form (i.e., as a single number).

1)
900,000 + 20,000 + 3,000 + 800 + 40 + 6
= 923,846
---
2)
7,000,000 + 800,000 + 30,000 + 9,000 + 600 + 30 + 4
= 7,839,634
---
3)
800,000 + 50,000 + 9,000 + 600 + 10 + 7
= 859,617
---
4)
8,000,000 + 100,000 + 30,000 + 6,000 + 600 + 90 + 4
= 8,136,694
---
5)
100,000 + 10,000 + 1,000 + 900 + 80 + 6
= 111,986
---
6)
9,000,000 + 200,000 + 20,000 + 5,000 + 300 + 60 + 8
= 9,225,368
---
7)
9,000,000 + 100,000 + 70,000 + 9,000 + 200 + 90 + 0
= 9,179,290
---
8)
4,000,000 + 600,000 + 80,000 + 6,000 + 100 + 50 + 6
= 4,686,156
---
9)
2,000,000 + 700,000 + 40,000 + 4,000 + 100 + 30 + 2
= 2,744,132
---
10)
900,000 + 20,000 + 7,000 + 700 + 30 + 0
= 927,730
---
11)
800,000 + 60,000 + 5,000 + 700 + 90 + 4
= 865,794
---
12)
7,000,000 + 600,000 + 60,000 + 3,000 + 200 + 80 + 2
= 7,663,282
---
13)
900,000 + 50,000 + 1,000 + 900 + 20 + 7
= 951,927
---
14)
4,000,000 + 300,000 + 60,000 + 4,000 + 900 + 40 + 1
= 4,364,941
---
15)
200,000 + 70,000 + 4,000 + 200 + 50 + 1
= 274,251

✔ Explanation:
Each expression is a sum of place values (hundred thousands, ten thousands, etc.). To write in standard form, we simply add all the values together. This helps understand how numbers are built from their expanded forms.
Let me know if you'd like this explained step-by-step for any specific problem!
Parent Tip: Review the logic above to help your child master the concept of expanded and standard form worksheet.
