Given the following numbers:

Ad libitum [116K]

The numbers π,2√5,√8,√3,√27 are real numbers, and the correct order of the numbers from least to greatest is √3, √8, π, 2√5, √27

<h3>How to order the numbers from least to greatest?</h3>

The list of numbers is given as:

π,2√5,√8,√3,√27

Evaluate each number:

$\pi = 3\frac{1}{7}$

$2\sqrt 5 = 2 * 2.2$

$2\sqrt 5 = 4.4$

Express as fraction

$2\sqrt 5 = 4 \frac 25$

$\sqrt{8} = 2.8$

Express as fraction

$\sqrt{8} = 2\frac 45$

$\sqrt{3} =1.7$

Express as fraction

$\sqrt{3} =1\frac{7}{10}$

$\sqrt{27} = 5.2$

Express as fraction

$\sqrt{27} = 5\frac15$

From the above computation, we have the following results

$\pi = 3\frac{1}{7}$

$2\sqrt 5 = 4 \frac 25$

$\sqrt{8} = 2\frac 45$

$\sqrt{3} =1\frac{7}{10}$

$\sqrt{27} = 5\frac15$

Order the numbers in ascending order

$\sqrt{3} =1\frac{7}{10}$

$\sqrt{8} = 2\frac 45$

$\pi = 3\frac{1}{7}$

$2\sqrt 5 = 4 \frac 25$

$\sqrt{27} = 5\frac15$

The above means that the correct order of the numbers from least to greatest is √3, √8, π, 2√5, √27
