Question

3000 millimetres to kilometre​

Answer 1

`1mm = 1 * {10}^( - 6) \\ 3000mm = x \\ \\ \\ x = 3000 * {10}^( - 6) \\ x = 0.003`

3000 millimetre = 0.003 kilometre

Answer 2

0.003 km

Explanation:

KM = MM / 1,000,000

x = 3,000mm / 1,000,000 = 0.003 km

There are also 0.000001 km in 1 mm, so in reverse,

0.000001

0.001 <- move to left 3 times (1,000)

0.003 km = 3,000 mm.
