Answer:
30
Step-by-step explanation:
Answer: 5km, 6000m, 8,000,000 mm, 7000000 cm
Note that:
1km = 1,000,000mm
1m = 1000mm
1cm = 10mm
Therefore,
5 km = 5 × 1,000,000mm = 5,000,000mm
7000,000 cm = 7,000,000 × 10 = 70,000,000mm
6,000 m = 6000 × 1000 = 6,000,000mm
Therefore, from the least to the greatest will be:
5km, 6000m, 8,000,000 mm, 7000000 cm
