    Answer:

    0.21

    Step-by-step explanation:

    The given expression is :

    0.5\times \sqrt{0.09}-2\sqrt{0.05}+\sqrt \frac{1}{4}

    We need to solve it.

    We know that,

    \sqrt{0.09}=0.3\ and\ \sqrt{0.05}=0.223

    So,

    0.5\times \sqrt{0.09}-2\sqrt{0.05}+\sqrt \frac{1}{4}=0.5\times 0.3-2\times 0.22+0.5\\\\=0.21

    or

    =\dfrac{21}{100}

    So, the value of the given expression is equal to 0.21.
