Let's solve the problem step by step.
Task:
Round each number to the
nearest hundred thousand.
---
Understanding Rounding to the Nearest Hundred Thousand:
- The
hundred thousands place is the 6th digit from the right.
- To round to the nearest hundred thousand, look at the
ten thousands place (the digit to the right of the hundred thousands place).
- If that digit is
5 or greater, round
up.
- If it's
less than 5, round
down.

Now, let’s go through each number:
---
1.
372,477
- Hundred thousands digit:
3
- Ten thousands digit:
7 → ≥ 5 → Round up
- 300,000 + 100,000 =
400,000
✔ 400,000
2.
497,385
- Hundred thousands digit:
4
- Ten thousands digit:
9 → ≥ 5 → Round up
- 400,000 + 100,000 =
500,000
✔ 500,000
3.
583,471
- Hundred thousands digit:
5
- Ten thousands digit:
8 → ≥ 5 → Round up
- 500,000 + 100,000 =
600,000
✔ 600,000
4.
492,274
- Hundred thousands digit:
4
- Ten thousands digit:
9 → ≥ 5 → Round up
- 400,000 + 100,000 =
500,000
✔ 500,000
5.
119,382
- Hundred thousands digit:
1
- Ten thousands digit:
1 → < 5 → Round down
- So, it stays

✔ 600,000
8.
857,374
- Hundred thousands digit:
8
- Ten thousands digit:
5 → ≥ 5 → Round up
- 800,000 + 100,000 =
900,000
✔ 900,000
9.
777,384
- Hundred thousands digit:
7
- Ten thousands digit:
7 → ≥ 5 → Round up
- 700,000 + 100,000 =
800,000
✔ 800,000
10.
