The simplified value of 0.002 $$\times$$​ 0.5 is:

Correct option is D

Given:

​ $0.002\times 0.5$​

Solution:

expressing the numbers :

0.002 =  $$2 \times 10^{-3}$$ 

0.5 = $$5 \times 10^{-1}$$ 

Now multiplying :

​$$(2 \times 10^{-3}) \times (5 \times 10^{-1}) = (2×5)×(10^{-3}×10^{-1})$$ 

$$= 10×10^{-4}$$ 

​$$10×10^{-4} = 10^{-3}$$ 

​Finally, $$10^{-3} = 0.001$$ 

10−3=0.00110^{-3} = 0.00110−3=0.00110^{-3}= 0.00110−3=0.001​The simplified value of $0.002\times 0.5$ is $0.001$.​
