Answer 2

1 mg in terms of tonnes using the scientific notation is $10^{-9}$.

Step-by-step explanation:

Given : One tonne is equal to 1000 kg.

To find : Express 1 mg in terms of tonnes using the scientific notation ? ​

Solution :

1 tonne = 1000 kg = $10^3$ kg

We know that,

1 kg = 1000 g = $10^3$ g

So, 1 tonne = $10^3\times 10^3$ g

We know,

1 g = 1000 mg = $10^3$  mg

i.e. 1 tonne = $10^3\times 10^3\times 10^3$ g

1 tonne = $10^9$ g

1 mg = $\frac{1}{10^9}$ tonnes

1 mg = $10^{-9}$ tonnes

Therefore, 1 mg in terms of tonnes using the scientific notation is $10^{-9}$.
