Answer:
0.4519km, 828m, 0.632km, 541.3m, 0.45km
Explanation:
km=1000*m. In this problem you flipped the two around. for example, for the petronas twin towers, you would do 451.9(m)/1000 to get 0.4519 km. for burj khalifa, you would do 0.828 (km) *1000 to get 828m. for kilometers to meters do (value) * (1000m/1km). for meters to kilometers do (value) * (1km/1000m)
