Order the following numbers from least to greatest.
–5.5 4.5 22/7
√4 –√20
a
–√20, –5.5, √4 , 4.5, 22/7
d
–√20, –5.5, 22/7, √4 , 4.5

-5.5        4.5

Step-by-step explanation:

Given:

The numbers to order from least to greatest is given as:

In order to compare these numbers, we have to convert them in same form.

Let us simplify each number in decimal form.

So, the least number is one which has the largest value with a negative sign.

Here, -5.5 is the least number.

The next smallest number is -4.47. So,

The next smallest number is 2. So,

The next smallest number is 3.14. So,

The greatest number is 4.5.

Therefore, the order from the least to greatest is:

-5.5 < < < < 4.5
