90000 dm - 6000 dam = 84000 dm
84000 dm a km = 84000 ÷ 10 ÷ 10 ÷ 10 ÷ 10 = 8.4 km
1 dam = 10 m
1 km = 1000 m
→ 1 km = 100 dam
6000 dam = 6000/100 km = 60 km
1 m = 100 cm
1 dm = 10 cm
→ 1 m = 10 dm
1000 m = 1 km
10(1000) dm = 1 km
10 000 dm = 1 km
90 000 dm = 90000/10000 km = 9 km

Explicación paso a paso:
90000 dm - 6000 dam = 84000 dm
84000 dm a km = 84000 ÷ 10 ÷ 10 ÷ 10 ÷ 10 = 8.4 km
1 dam = 10 m
1 km = 1000 m
→ 1 km = 100 dam
6000 dam = 6000/100 km = 60 km
1 m = 100 cm
1 dm = 10 cm
→ 1 m = 10 dm
1000 m = 1 km
10(1000) dm = 1 km
10 000 dm = 1 km
90 000 dm = 90000/10000 km = 9 km
