Assuming that you need to place the numbers on a number line;
1) Convert all numbers in one form, be it fraction or decimals
16/4 = 4
-2.7 = -2.7
1.75 = 1.75
1/5 = 0.2
2) Draw a number line with zero in the middle and positive numbers going to the right. The negative numbers go on left.
3) Place the decimal/fraction numbers into the number line, using a constant interval.

If you are considering all the vertices independently you will have a total of 8*10 = 80 triangles. You can figure out this way: the sum of the interior angles of a decagon = (2n-4)*right angles or (n-2)*triangles. So a decagon will form 8 triangles.

I think the answer would be 1932 tiles cubed, I think you might need help from someone else though, sorry.
