Chapter 1.3, Problem 42P

Order the numbers from least to greatest.

$1.875,\sqrt{64},-\sqrt{121}$

To determine

To Rearrange: The numbers given in the ascending order.

Answer to Problem 42P

  $-\sqrt{121}>1.875>8$

Explanation of Solution

Given:

First number $=1.875$

Second number $=\sqrt{64}$

Third number $=-\sqrt{121}$

Calculation:

First number $=1.875\mathrm{.....}\left(1\right)$

Second number $=\sqrt{64}=8\mathrm{....}\left(2\right)$

Third number $=-\sqrt{121}=-11\mathrm{.....}\left(3\right)$

From (1), (2), and (3)

Smallest number is $-11$

Greatest number is $8$

Now, arranging them from smallest/ least to greatest as:

  $-11>1.875>8$

i.e. $-\sqrt{121}>1.875>8$
