Question

Divide $\dfrac{2}{{1000}}$

Answer 1

Hint: First we have to define what the terms we need to solve the problem are. We know that whenever we have to divide any number by $10$ or $10$ or $10$ or other powers of $10$ then the decimal will be shifted towards the starting of the number and the number of numbers it crosses will depend upon the power of $10$.
For example: if the power of $10$ is $2$ then the decimal will shift two places before from its original place.

Complete step-by-step solution:
We have to divide $2$by $1000$ which we are going to divide by using the following method;
We know that whatever we have to divide any number by some power of $10$ then we shift the decimal in the backward direction of the number given and the number of places that we are shifting is equal to the power of $10$.
Now we are going to divide $2$ by $1000$. We can write $1000$ as ${10^3}$ so the power of $2$ by $10$ given in this problem is $3$. Now we are going to shift the place of the decimal given in the problem by $3$ places before the original position of the decimal.
Hence the result of the division of $\dfrac{2}{{1000}}$ is equal to $0.002$.

Note: We can always write any number which prerequisite does not contain any decimal as $1234.0$
And it is divided by $1234.0$ by $10$ by above solving methods we get $\dfrac{{1234.0}}{{10}} = 123.4$
We can also able to solve the above problem like 2 by \[1000\] is 0.2 by \[100\] and further 0.02 by 10 and hence \[0.002.\]
