15 75/45 = 16 30/45
X = 1st number
y = 2nd number
x + y = 200
x : y = 4 : 6
ok! let's substitute numbers!
4 * 10 : 6 * 10
40 : 60
40 + 60 = 200
100 ≠ 200
Too small!
That is exactly two times smaller than 200 so let's try 2 times greater than multiplying by 10
4 * 20 : 6 * 20
80 : 120
80 + 120 = 200
200 = 200
Now it says to find the larger number. Which is y.
x :y = 4 : 6 = 80 : 120
so, y is 120
y = 120
Answer : y = 120. The larger number is 120.

This is your answer
√3n+2+ √2n+1/n+1
In every side of the coin, there is a fifty fifty chance
of landing on the other side, so there is a probability of 0.50. In a deck of
cards, there are 52 cards with 26 clubs and another 26 for spades. So in every
random choice, there is a 1/26 probability of the card being chosen.
