notation.​

Answer 1

Answer:

1000000

it is because 1 mg 1000kg and 1 tonne is 1000g

Answer 2

Answer:

1 mg = 10⁻⁹ tonne

Step-by-step explanation:

1 tonne = 1000 kg = 10³ kg

1 kg = 1000 g = 10³ g

=> 1 tonne = 10³x10³ g

1 g = 1000 mg = 10³ mg

=> 1 tonne = 10³x10³x10³ mg

=> 1 tonne = 10⁹ mg

=> 1 mg = 10⁻⁹ tonne

(Note: mg = milligram; g = gram; kg = kilogram)
