To arrange numbers in descending order consists of putting them in order from greatest to least.
Examples
In each of these lists of numbers, the numbers are arranged in descending order:
9 , 8 , 7 , 6 , 5 , 4 , 3 , 2 , 1
45 , 23 , 15 , 12 , 9 , 7 , 5 , 3
200 , 120 , 90 , 60 , 40 , 30
23 , 11 , 7 , 3 , 0 , -3 , -8 , -12
Arrangement of quantities from largest to smallest.
Example
Consider these statistical results: 13, 10, 5, 19, 22, 17, 30.
Arranged in descending order, we get: 30, 22, 19, 17, 13, 10, 5.
