For 30 the place value is 3 x 10 or 3 tens so 3 is placed at the tens position

The place value of the digits are
For 4000 the place value is 4 x 1000 or 4 thousands so 4 is placed at the thousands position
For 200 the place value is 2 x 100 or 2 hundreds so 2 is placed at the hundreds position
For 50 the place value is 5 x 10 or 5 tens so 5 is placed at the tens position
For 9 the place value is 9 x 1 or 9 ones so 4 is placed at the ones position.
