2/3 - 1/4 ... let's find the common numbers 12 so new numbers would be 8/12 and 3/12 aka 11/12 + .. anyways it's 11/12 plus 2/3 x
45 because if he had any less, there would be left overs for either the 5 per page or 9 per page.
This graph is a V that is opening downward and the point is at the point (0,0)
De Morgan's law: (A∩B)' = A'∪B'
(S₁∩P)' = S'₁ ∪ P'
S'₁={P} ∪ {S₂}
P' ={ S₁} ∪ {S₂}
S'₁ ∪ P' ={P} ∪ {S₂} ∪ { S₁} ∪ {S₂}
(S₁∩P)' = S'₁ ∪ P' = SPACE
Y = 8. There is no solution.
