Question

Fill in the blanks:

$2\mathrm{m}5\mathrm{cm}=...........\mathrm{m}$

Answer 1

1 m = 100 cm
$\Rightarrow 1\mathrm{cm}=\frac{1}{100}\mathrm{m}$

$$\begin{gathered} 2\mathrm{m}5\mathrm{cm}=2\mathrm{m}+\frac{5}{100}\mathrm{m} \\ =2\mathrm{m}+0.05\mathrm{m} \\ =2.05\mathrm{m} \end{gathered}$$

Thus, $2\mathrm{m}5\mathrm{cm}=\underline{2.05}\mathrm{m}$​​​.
