Answer 2

The decimal expansion of $\dfrac{23}{2^3\times 5^{2} }$ is equal to 0.115.

Explanation:

We have,

$\dfrac{23}{2^3\times 5^{2} }$

To find, the decimal expansion of $\dfrac{23}{2^3\times 5^{2} }$ = ?

∴ $\dfrac{23}{2^3\times 5^{2} }$

= $\dfrac{23}{8\times 25 }$

$=\dfrac{23}{200}$

Multiplying numerator and denominator by 5, we get

$=\dfrac{23\times 5}{200\times 5}$

$=\dfrac{115}{1000}$

= 0.115

∴ The decimal expansion of $\dfrac{23}{2^3\times 5^{2} }$ = 0.115

Thus, the decimal expansion of $\dfrac{23}{2^3\times 5^{2} }$ is equal to 0.115.
