let the first number be a
the other number is 5/14 from the question
a x 5/14 = 20

30 people are already in the cabin.
If there’s 2/3 of the people that the cabin can carry, and 15 more can board, the 15 is the remaining 1/3, so to get the other 2/3 that we don’t know, you multiply 15 by 2, to get 30.
So all together, the cabin can carry 45 people.
Hope this helps!
