Answer:
4/15
Step-by-step explanation:
You add up all the balls for the bottom number(denominator), for the top number you put the amount of green balls (numerator)
They do not form a Pythagorean Triple.
If it was a Triple, 4^2+5^2 should equal 6^2.
4^2+5^2=16+25=41
6^2=36
41≠26
It doesn't work, therefore it is not a Pythagorean Triple.
