Let’s solve each part step by step.

Part 1: Converting Metric Units – Length

We need to convert between mm, cm, m, and km.

Remember:
- 1 cm = 10 mm → multiply cm by 10 to get mm
- 1 m = 100 cm → multiply m by 100 to get cm
- 1 km = 1000 m → multiply km by 1000 to get m

Now let’s do each problem:

1) 1.8 cm = ? mm
→ 1.8 × 10 = 18 mm

2) 0.2 cm = ? mm
→ 0.2 × 10 = 2 mm

3) 13 ½ cm = ? mm
→ 13.5 × 10 = 135 mm

4) 4.9 cm = ? mm
→ 4.9 × 10 = 49 mm

5) 1.6 m = ? cm
→ 1.6 × 100 = 160 cm

6) 2.61 m = ? cm
→ 2.61 × 100 = 261 cm

7) 0.3 m = ? cm
→ 0.3 × 100 = 30 cm

8) 4.07 m = ? cm
→ 4.07 × 100 = 407 cm

9) 1.9 km = ? m
→ 1.9 × 1000 = 1900 m

10) ¼ km = ? m
→ 0.25 × 1000 = 250 m

11) 3.28 km = ? m
→ 3.28 × 1000 = 3280 m

12) 5.802 km = ? m
→ 5.802 × 1000 = 5802 m

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

We’ll convert everything to the same unit (meters) to compare.

Box 1:
- 1020 m → already in meters
- 1.2 km → 1.2 × 1000 = 1200 m
- 19,000 cm → 19,000 ÷ 100 = 190 m

Largest: 1.2 km (1200 m) ← already circled in image

Box 2:
- 1.5 m → 1.5 m
- 128 cm → 128 ÷ 100 = 1.28 m
- 1520 mm → 1520 ÷ 1000 = 1.52 m

Largest: 1520 mm (1.52 m)

Box 3:
- 2730 m → 2730 m
- 36,000 cm → 36,000 ÷ 100 = 360 m
- 2.59 km → 2.59 × 1000 = 2590 m

Largest: 2730 m

Box 4:
- 3.8 m → 3.8 m
- 309 cm → 309 ÷ 100 = 3.09 m
- 3160 mm → 3160 ÷ 1000 = 3.16 m

Largest: 3.8 m

Part 3: Use >, <, or = to compare

Again, convert to same unit for comparison.

1) 1.5 m vs 127 cm
→ 1.5 m = 150 cm → 150 > 127 → >

2) 1.95 km vs 1564 m
→ 1.95 km = 1950 m → 1950 > 1564 → >

3) 28 mm vs 2.8 cm
→ 2.8 cm = 28 mm → =

4) 87 cm vs 0.9 m
→ 0.9 m = 90 cm → 87 < 90 → <

5) 1240 m vs 1.3 km
→ 1.3 km = 1300 m → 1240 < 1300 → <

6) 6.3 cm vs 69 mm
→ 6.3 cm = 63 mm → 63 < 69 → <

7) 145 mm vs 1.8 cm
→ 1.8 cm = 18 mm → 145 > 18 → >

8) 2.08 km vs 2080 m
→ 2.08 km = 2080 m → =

9) 3.4 m vs 309 cm
→ 3.4 m = 340 cm → 340 > 309 → >

10) 529 cm vs 5.6 m
→ 5.6 m = 560 cm → 529 < 560 → <
