## 🔢 Part 1: Round to the nearest 100

The rule for rounding to the nearest 100:
- Look at the tens digit.
- If it’s 5 or more, round up.
- If it’s 4 or less, round down.

We’ll go one by one:

---

1. 627

- Tens digit = 2 → less than 5 → round down
- Nearest 100 = 600

✔ Answer: 600

---

2. 489

- Tens digit = 8 → 5 or more → round up
- Nearest 100 = 500

✔ Answer: 500

---

3. 223

- Tens digit = 2 → less than 5 → round down
- Nearest 100 = 200

✔ Answer: 200

---

4. 880

## 🕒 Part 2: Draw clock hands — Time Passage

---

Problem 13:

> What time will it be in 4 hours 15 minutes?

First, look at the starting clock:

- Hour hand is on 9
- Minute hand is on 12 → so it’s 9:00

Add 4 hours 15 minutes:

- 9:00 + 4 hours = 1:00 PM (or 13:00)
- Then +15 minutes = 1:15

So, draw clock hands:
- Hour hand: slightly past 1 (since 15 min is 1/4 hour)
- Minute hand: pointing to 3 (which is 15 minutes)

✔ Final Answer: 1:15

*(You’d draw hour hand halfway between 1 and 2? Actually, no — since 15 minutes is exactly 1/4 of an hour, the hour hand should be a quarter of the way from 1 to 2. But for elementary level, often they just put it slightly past 1.)*

---

Problem 14:

> What time will it be in 3 hours 0 minutes?

Starting clock:

- Hour hand is between 7 and 8 → closer to 7
- Minute hand is on 3 → that’s 15 minutes

So starting time = 7:15

Add 3 hours:

- 7:15 + 3 hours = 10:15

Draw clock hands:
- Hour hand: slightly past 10 (since 15 min = 1/4 hour)
- Minute hand: pointing to 3

✔ Final Answer: 10:15
