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.

Compare 0.05 and 0.09
 By using the steps given above, the integral parts and tenths places are equal. By comparing the hundredth place, we get 5 < 9. Therefore, 0.05 < 0.09.
 So far we discussed about the comparison of two decimal numbers. Extending this, we can arrange the given decimal numbers in ascending or descending order.

4 m = \(\frac { 4 }{ 1000 } \)km = 0.004 km

 Given, height of the person = 165 cm.
Hence, the height of the person = \(\frac { 165 }{ 100 } \) = 1.65 m
Since, 1 cm = \(\frac { 1 }{ 100 } \) m = 0.01 m

(i) The place value of 7 in 0.37 is Hundredth.
(ii) The place value of 7 in 2.73 is Tenth.
(iii) The place value of 7 in 28.271 is Hundredth.

Place value of 6 in 53.61 is Tenths or \(\frac{1}{10}\)

\(1 \mathrm{~cm}=\frac{1}{100} m=0.01 \mathrm{~m}\)
16 cm = 16 x 1 cm
\(=16 \times \frac{1}{100} m \)
\(=\frac{16}{100} m=0.16 \mathrm{~m} \)

\(1 \mathrm{~mm}=\frac{1}{10} \mathrm{~cm}=0.1 \mathrm{~cm}\)
9 mm = 9 x 1 mm
\(=9 \times \frac{1}{10} \mathrm{~cm}=\frac{9}{10} \mathrm{~cm}\)
9 mm = 0.9 cm

\(1 \mathrm{~mm}=\frac{1}{10} \mathrm{~cm}=0.1 \mathrm{~cm}\)
5 mm = 5 x 1 mm
\(=5 \times \frac{1}{10} \mathrm{~cm}=\frac{5}{10} \mathrm{~cm}\)
5 mm = 0.5 cm

Four hundred four and five hundredths.
  = 404 + \(\frac { 5 }{ 100 } \)
  = 404 + 0 x \(\frac { 1 }{ 10 } \) + 5 x \(\frac { 1 }{ 100 } \) = 404.05

153 + 96 + 7 + \(\frac { 5 }{ 10 } \) + \(\frac { 2 }{ 1000 } \) = 256 + 5 x \(\frac { 1 }{ 10 } \) + 0 x \(\frac { 1 }{ 100 } \) + 2 x \(\frac { 1 }{ 1000 } \)
  = 256.502 (since hundredths place is not there, it is taken as '0' )
