Question

Write the following numbers in decreasing order 77890, 78999, 79009 and 73535.

Answer 1

Hint: Compare the ten thousand and thousand’s place of each number i.e. compare the first 2 digits of each given number and find the largest number. Thus arrange the numbers from the largest to smallest.

Complete step-by-step answer:
Numbers are said to be in the decreasing order when they are arranged from the largest to the smaller number. Similarly, numbers are said to be in ascending order when they are arranged from the smallest to the largest number.
We have been given 5 digit numbers to arrange 77890, 78999, 79009, 73535. Before we look on to this let us look into few examples,
Eg: - 3, 8, 1, 5, 22, 32, 10, 50 etc.
Let us arrange in descending order, we get
50, 32, 22, 10, 8, 5, 3, 1
If we arrange the same in ascending order, we get,
1, 3, 5, 8, 10, 22, 32, 50
Now let us take a look at our given numbers 77890, 78999, 79009, 73535. All are 5 digit numbers. So let us compare the ten thousand and thousand’s place of all the digits.
77890, 78999, 79009, 73535
We have found the first 2 digits of each number. From this we can say that 79 is the largest number followed by 78, 77 and 73. Thus we can arrange them as,
79009, 78999, 77890, 73535
We can put the symbol as (>) from largest to smallest.
79009 > 78999 > 77890 > 73535
Thus we got the decreasing order of the number.

Note: If for example the first 2 digits of a number is equal to another number, then compare the hundredth place eg:- 77003 and 77985. Thus comparing them 77 is the same in both. So move to the hundredth place. So 77985 is the largest among them.
