Is √6/8. rational or irrational?

Ipatiy [6.2K]

<h2>Answer:</h2>

The number is irrational.

<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>

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

-------------------------------------------------------------------------------------------------------

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

Charlie watched 1 3 of a movie in the morning, and he watched some more at night. By the end of the day, he still had 2 5 of the

Finger [1]

Answer: 4/15 of the movie

Step-by-step explanation:

In the morning, Charlie watched ¹/₃ of a movie. He then watched some more at night.

At the end of the day, he still had ²/₅ of the movie to watch.

The proportions of an item must always add up to one. This means that if you added the 1/3 to the 2/5 and then to the fraction Charlie watch at night, they should add up to one.

¹/₃ + ²/₅ + x = 1

x = 1 - ¹/₃ - ²/₅

$x = \frac{15 - 5 - 6 }{15} \\\\x = \frac{4}{15}$
