Math worksheet for converting metric units of weight and volume, including conversion problems, comparing amounts, and identifying the largest value in each box.

Let's solve this step-by-step. The worksheet is about converting metric units of weight (mass) and volume, and then comparing values.

---

🔹 Part 1: Convert kilograms to grams and liters to milliliters

#### 🔸 Conversion rules:
- 1 kg = 1000 g
- 1 L = 1000 mL

So:
- To convert kg → g: Multiply by 1000
- To convert L → mL: Multiply by 1000

---

#### ✔ Conversions:

1) 1.4 kg = $1.4 \times 1000 = \boxed{1400}$ g
2) 2.65 kg = $2.65 \times 1000 = \boxed{2650}$ g
3) 0.3 kg = $0.3 \times 1000 = \boxed{300}$ g
4) 4.725 kg = $4.725 \times 1000 = \boxed{4725}$ g
5) 5.08 kg = $5.08 \times 1000 = \boxed{5080}$ g
6) $3\frac{1}{4}$ kg = $3.25$ kg → $3.25 \times 1000 = \boxed{3250}$ g
7) 1.7 L = $1.7 \times 1000 = \boxed{1700}$ mL
8) 2.27 L = $2.27 \times 1000 = \boxed{2270}$ mL
9) $2\frac{1}{4}$ L = $2.25$ L → $2.25 \times 1000 = \boxed{2250}$ mL
10) 0.84 L = $0.84 \times 1000 = \boxed{840}$ mL
11) 8.36 L = $8.36 \times 1000 = \boxed{8360}$ mL
12) 6.05 L = $6.05 \times 1000 = \boxed{6050}$ mL

🔹 Part 2: Which is the most? Circle the largest amount in each box

We need to convert all values to the same unit for comparison.

---

#### 🔸 Box 1:
- 1.5 kg = $1.5 \times 1000 = 1500$ g
- 1280 g
- 960 g

→ Largest: 1500 g → So 1.5 kg is the largest ✔ (already circled)

---

#### 🔸 Box 2:
- 2.3 L = $2.3 \times 1000 = 2300$ mL
- 2150 mL
- 380 mL

→ Largest: 2300 mL → So 2.3 L is largest ✔

---

#### 🔸 Box 3:
- 370 g
- 0.4 kg = $0.4 \times 1000 = 400$ g
- 2300 g

→ Largest: 2300 g ✔

---

#### 🔸 Box 4:
- 3.25 L = $3.25 \times 1000 = 3250$ mL
- 3300 mL
- 3200 mL

→ Largest: 3300 mL ✔

So, circle:
- 1.5 kg (already done)
- 2.3 L
- 2300 g
- 3300 mL

🔹 Part 3: Compare using >, <, or =

Convert both sides to the same unit.

1) 1.6 L vs 1500 mL
- 1.6 L = $1.6 \times 1000 = 1600$ mL
- 1600 mL > 1500 mL → >

2) 1762 mL vs 1.09 L
- 1.09 L = $1.09 \times 1000 = 1090$ mL
- 1762 mL > 1090 mL → >

3) 1.2 kg vs 900 g
- 1.2 kg = $1.2 \times 1000 = 1200$ g
- 1200 g > 900 g → >

4) 728 g vs 0.9 kg
- 0.9 kg = $0.9 \times 1000 = 900$ g
- 728 g < 900 g → <

5) 7520 mL vs 7.6 L
- 7.6 L = $7.6 \times 1000 = 7600$ mL
- 7520 mL < 7600 mL → <

6) 1415 mL vs 1.5 L
- 1.5 L = $1.5 \times 1000 = 1500$ mL
- 1415 mL < 1500 mL → <

7) 2850 g vs 2.85 kg
- 2.85 kg = $2.85 \times 1000 = 2850$ g
- 2850 g = 2850 g → =

8) $ \frac{1}{4} $ L vs 250 mL
- $ \frac{1}{4} $ L = 0.25 L = $0.25 \times 1000 = 250$ mL
- 250 mL = 250 mL → =

9) 5.07 kg vs 5100 g
- 5.07 kg = $5.07 \times 1000 = 5070$ g
- 5070 g < 5100 g → <

10) 3270 g vs 0.327 kg
- 0.327 kg = $0.327 \times 1000 = 327$ g
- 3270 g > 327 g → >
