Question

Read the decimal and write the number name:

$9.999$

Answer 1

To read a decimal number, first, read the digits to the left of the decimal point as a whole number and then read the digits to the right of the decimal point separately.

Example:- If $26.63$ is a decimal number then $26$ is a whole number read it as twenty six and digits after point needs to be read separately like six three (i.e., twenty six point six three).

We have $9.999$

Here $9$ is whole number and $999$ is a decimal part.

So, we can read it as, Nine point nine nine nine or nine hundred ninety nine thousand.
