Answer 2

This number can also be written as

$3 \frac{9999999}{10000000}$ its my logic

3.9999999 -> (you can say this) 4.0000000 or 4

Example: Think you have been given ₹4,00,056
And you have been asked how many ₹ you have been given? Then you will answer it by round offing 4 lakhs not 4,00,056!

It is called "round off"
