67 kg = 67 kg × 1×10⁶ mg / 1 kg

67 kg = 6.7×10⁷ mg.

Explanation:

The following data were obtained from the question:

Mass in Kg = 67 kg

Mass in mg =.?

Thus, we can obtain the mass in milligrams (mg) as follow:

1 kg = 1×10⁶ mg

Therefore,

67 kg = 67 kg × 1×10⁶ mg / 1 kg

67 kg = 6.7×10⁷ mg

Therefore, 67 kg is equivalent to 6.7×10⁷ mg

the answer is 0.8m.
