Answer:

0

Step-by-step explanation:

The equation will be -4.5 + 4.4 - 6.7 +6.8 because the positive and negative will make a negative and so you solve the equation. Combine positives(4.4 and 6.8) and should get 11.2 then combine the negatives and get -11.2 and then you subtract the two numbers and get 0.

Order the following numbers from least to greatest.

zaharov [31]

Answer:

-5.5 $-\sqrt{20}$ $\sqrt4$ $\frac{22}{7}$ 4.5

Step-by-step explanation:

Given:

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

$-5.5, 4.5, 22/7,\sqrt4,-\sqrt{20}$

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

Let us simplify each number in decimal form.

$-5.5 = -5.5\\\\4.5=4.5\\\\\frac{22}{7}=3.14\\\\\sqrt4=2\\\\-\sqrt{20}=-\sqrt{5\times 2^2}=-2\sqrt5=-4.47$

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, $-\sqrt{20}$

The next smallest number is 2. So, $\sqrt4$

The next smallest number is 3.14. So, $\frac{22}{7}$

The greatest number is 4.5.

Therefore, the order from the least to greatest is:

-5.5 < $-\sqrt{20}$ < $\sqrt4$ < $\frac{22}{7}$ < 4.5
