1.
6.4 (decimal number) \(=6+4 \times \frac{1}{10}=6+\frac{4}{10}
\)
\(=\frac{60+4}{10}=\frac{64}{10}
\)
2.
6 + \(\frac { 0 }{ 10 } +\frac { 0 }{ 100 } +\frac { 9 }{ 1000 } \)
= \(6+0\times \cfrac { 1 }{ 10 } +0\cfrac { 1 }{ 100 } +9\times \cfrac { 1 }{ 1000 } \)
= 6.009
3.
\(1 \mathrm{~cm}=\frac{1}{100} m=0.01 \mathrm{~m}\)
6 m 6 cm = 6 m + 6 cm
= 6m + 6 x 1 cm
\(=6 m+6 \times \frac{1}{100} m=6 m+\frac{6}{100} m\)
= 6 m + 0.06 m = 6.06 m
4.
\(1 \mathrm{~cm}=\frac{1}{100} m=0.01 \mathrm{~m}\)
7 cm = 7 x 1 cm
\(=7 \times \frac{1}{100} m=\frac{7}{100} m\)
7 cm = 0.07 m
5.
\(1 \mathrm{~mm}=\frac{1}{10} \mathrm{~cm}=0.1 \mathrm{~cm}\)
375 mm = 375 x 1 mm
\(=375 \times \frac{1}{10} \mathrm{~cm}=\frac{375}{10} \mathrm{~cm}\)
375 mm = 37.5 cm
