Is √6/8. rational or irrational?
Ipatiy [6.2K]
<h2>Answer:</h2>

<em>The number is </em><u><em>irrational</em></u><em>.</em>

<h2>Step-by-step explanation:</h2>

<h3>1. Convert to decimal.</h3>

\sqrt{\frac{6}{8} } =\sqrt{0.75} =0.8660254038...

<h3>2. Conclude.</h3>

<em>Since this number shows to have infinite decimal figures, it cannot be represented as the ratio of 2 integers. Hence, the number is </em><u><em>irrational</em></u><em>.</em>

<u><em>-------------------------------------------------------------------------------------------------------</em></u>

<em>Note.</em><em> In case the number expressed in the question was </em>\frac{\sqrt{6} }{8}, the answer  would still be <u><em>irrational</em></u><em>, for the same reasons explained above</em>.
