The whole number parts of the three decimal numbers are equal.
The digits at tenths place are also equal.
The digits at hundredths place are 0, 1 and 5. Here 0 < 1 < 5
Therefore, the ascending order is 4.90, 4.91, 4.95.
2.
Compare 99.56 and 99.65
Here the whole number parts of the given two numbers are equal.
Comparing the digits at tenths place, we get 5 < 6.
Therefore, 99.56 < 99.65
3.
Compare 8.36 and 6.29
Comparing the whole number part, we get 8 > 6.
Therefore, 8.36 > 6.29
4.
| Tens | Ones | Tenths | Hundredths | Thousandths |
| 4 | 6 | 7 | 2 | 6 |
40 + 6 + \(\frac { 7 }{ 10 } +\frac { 2 }{ 100 } +\frac { 6 }{ 1000 } \) = 46.726
5.
3983 m = \(\frac { 3983 }{ 1000 } \)km = 3.983 km
So, Praveen's trekking record is 0.004 km, 0.028 km, 0.537 km, 3.983 km.
Since, 1m = \(\frac { 1 }{ 1000 } \)km = 0.001 km
