Answer:
We are required to order the numbers from greatest to least.
So, according to the options:
1. 9.129, 9.37, 9.3, 9.219
Since, the number of digits after the decimal place are not same, so we make them equal by adding 0 at the end. SO, we have,
9.129, 9.370, 9.300, 9.219
As, the ones place in each of the number is same, we look at the digit after the decimal.
Now, 9.370 and 9.300 have the same number after the decimal, so we look at the next number i.e 7 and 0 respectively.
As 7 > 0, so we get 9.370 > 9.300.
Hence, the order becomes 9.370, 9.300, 9.219, 9.129.
2. 0.012, 0.100, 0.001, 0.101
Again, as the ones place in each of the number is same, we look at the digit after the decimal.
Now, 0.101 and 0.100 have the same number till two places after the decimal, so we look at the next number i.e. 1 and 0 respectively.
As 1 > 0, so we have 0.101 > 0.100
Hence, the order becomes 0.101, 0.100, 0.012, 0.001.
3. 5.132, 5.123, 5.312, 5.231
Again, as the ones place in each of the number is same, we look at the digit after the decimal.
Now, 5.132 and 5.123 have the same number after the decimal, so we look at the next number i.e. 3 and 2 respectively.
As 3 > 2, so we get 5.132 > 5.123.
Hence, the order is 5.312, 5.231, 5.132, 5.123.
4. 62.905, 62.833, 62.950, 62.383
As the ones place in each of the number is same, we look at the digit after the decimal.
Now, 62.905 and 62.950 have the same number after the decimal, so we look at the next number i.e. 0 and 5 respectively.
As 5 > 0, so we get 62.950 > 62.905.
Hence, the order becomes 62.950, 62.905, 62.833, 62.383.
