What is a decimal amount that ends or divides evenly?
A whole number.

In the decimal numbering system, if the number ends in 0 or 5 it is evenly divisible by 5. If it ends in any other number it is not.
Why is 5615 not prime?
The definition of a prime number is a whole number greater than 1, that can be divided evenly only by 1 and itself. 5615 ÷ 5 = 1123 (5 divides evenly into 5615, therefore not a prime number).
What number divides into 324 and 630 and 228 with no remainder but does not divide evenly into 369?
That would be the number 2. 324/2 = 162. 630/2 = 315. 228/2 = 114. Since 369 ends with an odd number it cannot possibly be evenly divisible by 2.
How can you relate decimals with rationals?
-- Any decimal that ends is a rational number. -- Any decimal that never ends may or may not be a rational number. -- The decimal representation of an irrational number never ends.

How is 4230 diveded evenly by 2 5 and 10?
Any number that ends with a "0" (apart from 0 itself) will evenly divide by 10. We do this by removing the zero.So 4230/10 = 423.Any number which evenly divides by 10 will also evenly divide by both 2 and 5. This is because 2 and 5 are both factors of 10.4230/5 = 846.4230/2 = 2115.
