EXERCISE 2.5

The decimal number $200.03$ in the expanded form is $\left(2\times 100\right)+\left(0\times 10\right)+\left(0\times \_\_\_\_\_\right)+\left(0\times \frac{1}{10}\right)+\left(3\times \frac{1}{100}\right)$

If $2.034$ is expressed in expanded form as $\left(2\times 1\right)+\left(0\times \frac{1}{\mathrm{m}}\right)+\left(3\times \frac{1}{\mathrm{n}}\right)+\left(4\times \frac{1}{\mathrm{k}}\right)$, then find the value of $\mathrm{k}$.
