Grade 5 Math worksheet focusing on rounding numbers to the nearest 10, 100, and 1000, designed for educational practice.

Let’s go through each problem step by step.

We are rounding numbers to the nearest 10, 100, or 1000 — but in this worksheet, all problems ask for rounding to either 10 or 100 (no 1000s here).

Rule reminder:
- To round to the nearest 10, look at the ones digit:
- If it’s 5 or more → round up
- If it’s less than 5 → round down
- To round to the nearest 100, look at the tens digit:
- If it’s 5 or more → round up
- If it’s less than 5 → round down

---

A. 21 → Round to nearest 10
Ones digit is 1 → less than 5 → round down → 20

B. 971 → Round to nearest 100
Tens digit is 7 → 7 ≥ 5 → round up → 971 → 1000? Wait — let’s think:
Nearest hundreds around 971 are 900 and 1000.
Since tens digit is 7 (≥5), we round UP from 900 to 1000 → 1000

Wait — actually, 971 is between 900 and 1000. The tens digit is 7, so yes — round up to 1000. Correct.

C. 91 → Round to nearest 10
Ones digit is 1 → <5 → round down → 90

D. 92 → Round to nearest 10
Ones digit is 2 → <5 → round down → 90

E. 722 → Round to nearest 10
Ones digit is 2 → <5 → round down → 720

F. 12875 → Round to nearest 100
Look at tens digit: 7 → ≥5 → round up
So 12875 → look at hundreds place: 8 → becomes 9 → so 12900
Check: 12875 is between 12800 and 12900. Tens digit 7 → round up to 12900 → 12900

G. 16345 → Round to nearest 100
Tens digit is 4 → <5 → round down
Hundreds digit is 3 → stays 3 → so 16300
→ 16300

H. 75477 → Round to nearest 100
Tens digit is 7 → ≥5 → round up
Hundreds digit is 4 → becomes 5 → so 75500
→ 75500

I. 36936 → Round to nearest 100
Tens digit is 3 → <5 → round down
Hundreds digit is 9 → stays 9 → so 36900
→ 36900

J. 45782 → Round to nearest 100
Tens digit is 8 → ≥5 → round up
Hundreds digit is 7 → becomes 8 → so 45800
→ 45800
