The complete place value chart is shown in the attached image (the colored one)
The drawing will be a place-value chart as attached (the black and white one)
Since we are looking for a three-digit number, therefore, our number will occupy the ones, tens and hundreds position.
There are several 3-digit numbers that could be formed from the numbers 2,9 and 4.
<u><em>Some of these numbers are:</em></u><u>249 :</u> the 2 will be written in the hundreds column, the 4 in the tens column and the 9 in the ones column.
<u>492 :</u> the 4 will be written in the hundreds column, the 9 in the tens column and the 2 in the ones column.
<u>924 :</u> the 9 will be written in the hundreds column, the 2 in the tens column and the 4 in the ones column.
Hope this helps :)
