Descending Order
When we arrange things in order, from a higher value to a lower value, it is known as the descending order or the decreasing order. Descending is something similar to what we do while sliding down a ramp. When we slide down, we keep on decreasing our height from the ground. Hence, we are known to "descend" to the ground. In this lesson, we will learn all about the descending order.

What is Descending Order?
Arranging in descending order means arranging any data like numbers, alphabets, quantities, lengths, etc., from the highest to the lowest. In other words, when we arrange things in an order from a higher value to a lower value, they are said to be in descending order. Numbers like whole numbers, natural numbers, integers, fractions, decimals can be arranged in descending order. For example, let us arrange {7,3,9,2} in descending order. We will start with the largest number and move towards the smaller numbers one by one. These numbers, when arranged in descending order, are written as: {9,7,3,2}.
Descending Order Symbol
The symbol used to write numbers in descending order is ">." It represents if the sequence is in a decreasing or increasing order. For example, let us arrange the numbers 2, 4, 6, 1, 5, and 7 in descending order. When we arrange these numbers in descending order, the symbol is placed in the following way, where the open end faces towards the bigger number: 7 > 6 > 5 > 4 > 3 > 2 > 1.
Rules of Descending Order
Backward counting involves arranging numbers in descending order and forward counting involves arranging the numbers in ascending order. However, a certain number of rules need to be followed while arranging any items in descending order. The rules are as follows:
 The first number should always be the largest number.
 The numbers should always be in order from the largest to the smallest.
 The last number should always be the smallest.
Decimals in Descending Order
Decimals are arranged in ascending order by looking at the digits from left to right according to the place value of decimal numbers. First, we look at the whole number part. If the digit in the whole number part is the same for two or more numbers, then we look at the digit at the tenth place of the number (i.e., the first digit to the right of the decimal point). If the digit in the tenths place is also the same, then we look at the digit at the hundredth place and so on. This is how we arrange decimals in descending or decreasing order. For example, 5.9 > 3.67 > 2.45 > 2.41 > 2.07 > 1.99 shows the arrangement of decimal numbers in descending order.
Solved Examples on Descending Order

Example 1: Emma and her friends made a list of the number of trees in their neighborhood as follows: {10,19,8,17,7,23}. Arrange the list in descending order.
Solution:
Descending means an arrangement from the highest to the lowest. Hence, the number of trees will be arranged in descending order as follows:
∴ {23,19,17,10,8,7}

Example 2: In a school, a teacher recorded the heights of five students in her class. The heights are 3 feet 7 inches, 3 feet 4 inches, 3 feet 2 inches, 4 feet 2 inches, and 3 feet 8 inches. Arrange the heights in descending order.
Solution:
To arrange the heights in descending order, we start with the tallest student. The heights in descending order are 4 feet 2 inches, 3 feet 8 inches, 3 feet 7 inches, 3 feet 4 inches, and 3 feet 2 inches.
Practice Questions on Descending Order
FAQs on Descending Order
How Do you Arrange in Descending Order?
Descending order is an arrangement of numbers from the largest to the smallest. We start arranging the numbers by placing the largest number first and move towards the smaller numbers one by one. For example, if we arrange the numbers, 63, 99, 10, 87, 35 in descending order, we write them as: 99, 87, 63, 35,10.
What is a Descending Order Sign?
The symbol used to arrange numbers in descending order is ">". When we arrange numbers in descending order, the symbol is placed in a way such that the open end faces towards the bigger number. For example, here is a list of numbers arranged in descending order. 37 > 26 > 15 > 4 > 3 > 2 > 1.
What is the Difference Between Ascending And Descending Order?
Ascending order is the arrangement of numbers from the smallest to the largest. For example, the following numbers are in ascending order: 3,15, 28, 49. Descending order is an arrangement of numbers from the largest to the smallest. For example, the numbers: 45, 32, 26, 12 are arranged in descending order.
How to Arrange Decimals in Descending Order?
Decimals are arranged in descending order by looking at the digits from left to right. First, we compare the nondecimal part and arrange it in descending order. Now, for the ones which have the same nondecimal part, we need to compare the decimal part. We do this according to the place value of decimal numbers. We know that for the numbers 2.45 and 2.41, the nondecimal part is the same. So, we compare the decimal part. After comparing 0.45 and 0.41, we can see that 0.45 is the higher one. Hence, 2.45 will come before 2.41. For example, 5.9 > 3.67 > 2.45 > 2.41 > 2.07 > 1.99 shows the arrangement of decimal numbers in descending order.
Is Ascending Order Smallest to Largest?
Yes, when we arrange things in an order, from a lower value to a higher value, it is known as the ascending order or the increasing order. In this arrangement, we place the smallest value first, and move towards the larger numbers one by one. For example, the numbers: 3, 5, 14, 27 are arranged in ascending order.
