The nucleus contains the genetic material of an eukaryotic cell.
Answer:

Step-by-step explanation:
we know that
The <u>Least Common Multiple</u> (LCM) of a group of numbers is the smallest number that is a multiple of all the numbers.
we have
15,18 and 25
Decompose the numbers in prime factors



Multiply common and uncommon numbers with their greatest exponent
so
The LCM is equal to


5x + 4x = 720
9x = 720 (divide by 9)
X= 80
In order to get the bigger ratio, which is 5, you would substitute x for 80. (I'm bad at explaining)
Work:
5(80)= 400
8 ÷ 544 = 0.0147058824, 544 ÷ 8 = 68
