First can be a trophy second can be a gold metal and third can be a silver metal.
Here's how to do dividing in a certain ratio:
-- You want to divide up the whole thing in the ratio of
4 parts, 5 parts, and 9 parts.
-- How many parts all together ? (4 + 5 + 9) = 18 parts all together.
-- The whole thing is 180, and that's 18 total parts.
So each part is (180/18) = 10 degrees.
4 parts = (4 x 10) = 40
5 parts = (5 x 10) = 50
9 parts = (9 x 10) = 90.
Check: (40 + 50 + 90) = 180 . yay!

For the second one, I think there are some words missing.
The answer is -125. Get this by taking (-5)(-5)(-5)
