and the number got by interchanging the digits in its tenth's and thousandth's this place. What do we get? What is the difference of these two numbers?

Accepted Answer

We have the number $10.864$ .

Now, interchanging the digits in tenth's and thousandth's place of the above number we get $10.468$ .

Thus, adding the above numbers that is,

$= 10.864 + 10.468$

Writing these decimals in column form with decimal alignment, we get:

$\begin{matrix} 1 & 0 . & 8 & 6 & 4 \\ + & 1 & 0 . & 4 & 6 & 8 \end{matrix} \begin{matrix} 2 & 1 . & 3 & 3 & 2 \end{matrix}$

Therefore, adding both the numbers we get $21.332$ .

Now, subtracting the numbers $10.864$ and $10.468$ .

That is, $10.864 - 10.468$

Writing these decimals in column form with decimal alignment, we get:

$10.864$

Hence, the difference of these two numbers is $0.396$ .

We add $10.864$ and the number got by interchanging the digits in its tenth's and thousandth's this place. What do we get? What is the difference of these two numbers?
