To compare these numbers, you must first put them into one format. Since you have mixed numbers, you may have to find and use the LCD.

-2.5, 1/5, 10, -12/4, 18/5, 10 could be simplified somewhat immediately:

-2.5, 1/5, 10, -3, (3 3/5) This set of numbers is simple enough so that you could rearrange them in ascending order mentally:

-3, -2.5, 1/5, (3 3/5), 10

In this case the number of elements in this set is odd, so all you have to do is to select the MIDDLE element: 1/5.

The median is 1/5.

You MUST learn this procedure (arranging the set elements in ascending order and selecting the middle element) so that you can apply it yourself.

$\frac{ - 1}{5} \times \frac{4}{7}$

$\: \: \: \: \: \frac{ - 4}{35}$

12

$\frac{ - 1}{2} \times \frac{4}{5}$

$\frac{ - 2}{5}$

13

$\frac{ - 3}{2} \times \frac{7}{ - 10}$

$\frac{21}{20}$

14

$\frac{1}{2} \times \frac{7}{8}$

$\frac{7}{16}$

15

$\frac{ - 9}{5} \times \frac{1}{2}$

$\frac{ - 9}{10}$

16

$\frac{ - 32}{9} \times \frac{1}{3}$

$\frac{ - 32}{27}$

17

$\frac{ - 2}{1} \div \frac{ - 19}{5}$

$\: \: \: \: \: \: \frac{ - 2}{1} \times \frac{5}{ - 19}$

$\: \: \: \: \frac{ - 10}{19}$

18

$\frac{1}{9} \div \frac{ - 4}{3}$

$\frac{1}{9} \times \frac{3}{ - 4}$

$\frac{ - 1}{12}$

19

$\frac{13}{7} \div \frac{23}{4}$

$\frac{13}{7} \times \frac{4}{23}$

$\frac{52}{161}$

20

$\frac{ - 37}{10} \div \frac{9}{4}$

$\frac{ - 37}{10} \times \frac{4}{9}$

$\frac{ - 74}{45}$

Saint Petersburg, Russia and Anchorage, Alaska, both have approximately the same latitude of 60 degrees. That means you can reac

user100 [1]

Answer:

Distance from Anchorage (longitude 150 degrees W) to Saint Petersburg (longitude 30 degrees E) = 10,002.47 KM

Step-by-step explanation:

As earth is a sphere of radius 6371 km.

Therefore at 60 degree latitude, the radius of circle can be calculated as shown below:

= 6371 * Cos 60

= 3185.5 KM

Saint Petersburg is nearly 180 degree about Anchorage by flying directly east.

So Distance from Anchorage (longitude 150 degrees W) to Saint Petersburg (longitude 30 degrees E) can be calculated as shown below:

= (180 * 2 * 3.1416 * 3185.5) / 360

= 10,002.47 KM
