100 cm = 1 m
1000 m = 1 km
→ 1000 x 100 cm = 1 km
→ 100000 cm = 1 km
→ To convert cm to km, divide by 100000
→ 86000 cm = 86000 ÷ 100000 km = 0.86 km

Answer: 86,000 cm = 0.86 km
(86,000 cm) x (1 meter / 100 cm) x (1 km / 1,000 meters) =[ (86,000) / (100 x 1,000) ] x (cm - meter - km / cm - meter) =0.86 km
This is a table that shows how to convert distances:Kilometer (km)Hectometer (hm)Decameter (dam)Meter (m)Decimeter (dm)Centimeter (cm)Mellimeter (mm)As you go down the list you multiply by 10 each step!So 1 kilometer is 10 Hectometers. 10 Hectometers are 100 Decameters.0.5 Hectometers are 5 Decameters or 50 Meters.Now as you go from bottom towards the top you DIVIDE by 10 each step.So 100 Millimeters are 10 centimeters or 1 decimeter or 0.1 Meter.Hence, 86000 cm are 0.86 km.86000 divided by 100000!
18000 out of 86000 is about 20.93%.
86000 in scientific notation is 8.6 x 10^4
