To arrange the numbers - 1011, 1001, 1111, 1101 - in descendig order we must compare the digits of all the numbers begining with the digits at the highest place value.

Since all the numbers have 1 in the thousands place, we compare the digits in the hundreds place, tens and finally ones place.

On comparing the digits of the numbers we can arrange the numbers in descending order:

1111 > 1101 > 1011 > 1001
