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

Lola and Brandon had a running race. They ran 3/10 of a mile. Lola was in the lead for 4/5 of the distance. For what fraction of
Kruka [31]

Answer:

Lola was in lead for \frac{6}{25} of a mile.

Step-by-step explanation:

We have been given that Lola and Brandon had a running race. They ran 3/10 of a mile. Lola was in the lead for 4/5 of the distance.

To find the fraction of a mile for which Lola was in the lead, we need to find 4/5 of 3/10 as:

\text{Fraction for which Lola was in lead}=\frac{3}{10}\times\frac{4}{5}

\text{Fraction for which Lola was in lead}=\frac{3}{5}\times\frac{2}{5}

\text{Fraction for which Lola was in lead}=\frac{3\times2}{5\times5}

\text{Fraction for which Lola was in lead}=\frac{6}{25}

Therefore, Lola was in lead for \frac{6}{25} of a mile.
