 Hello and welcome to this session. In this session we discuss the following question which says arrange the following decimals in a descending order 2.2, 2.202, 2.02, 2.002 and 0.22. Let's see the solution now. The given decimals are 2.2, 2.202, 2.02, 2.002 and 0.22. Now we need to arrange these decimals in a descending order. So first of all we will convert these decimals into right decimals. That is the decimals having the same number of decimal places. So 2.200, 2.202, 2.020, 2.002, 0.220. So we have converted the given decimals into right decimals. That is they all have now the same number of decimal places. That is 3. Now we compare the whole number part of these decimal numbers. Now the first 4 decimal numbers have the same whole number part. That is 2. But the last decimal number that is 0.220 has the whole number part as 0 and so it would be the smallest of all the decimals. Now next we will compare the 10th digit of the decimal numbers. 10th digit of these 2 decimal numbers is same which is 2. Then the 10th digit of these 2 decimal numbers is also same which is 0. First let's consider the decimal numbers 2.200 and 2.202. Here the whole number parts are same. Then the 10th digits are also same. Next consider the 100th digit which is also same. Now consider the 1000th digit. Now the 1000th digit in this decimal number is greater than this. So 2.202 is greater than 2.200. So we have compared these 2 decimal numbers. Now consider these 2 decimal numbers that is 2.020 and 2.002. Here also the whole number parts are same. Then the 10th digits are also same. Now consider the 100th digit. Now the 100th digit of this number is greater than the 100th digit of this decimal number. So we have 2.020 is greater than 2.002. Now consider these 2 decimal numbers that is 2.200 and 2.020. Let's compare these 2 decimal numbers. Here the whole number parts are same. Then let's compare the 10th digit. The 10th digit of this number is greater than the 10th digit of this number. So we have 2.200 is greater than 2.020. From these results we get 2.202 is greater than 2.200 which is greater than 2.020 greater than 2.002. And we know that the decimal number 0.220 is the smallest of all. So we can write it here. So we have got the descending order of the given decimal numbers that is we have 2.202 is greater than 2.2 which is greater than 2.02 which is greater than 2.002 and this is greater than 0.22. This is the required descending order of the given decimal numbers. This is our final answer. So this completes the session. Hope you have understood the solution of this question.
