Let's assume that Baker Sam made a total of x boxes of mooncakes.
He gave 2/5 of the mooncakes to QQ Home, which is (2/5)*x = 2x/5 boxes.
So, the remainder of mooncakes is x - 2x/5 = (5x - 2x)/5 = 3x/5 boxes.
Baker Sam gave 4/9 of the remainder to KK Home, which is (4/9)*(3x/5) = (4*3x)/(9*5) = 12x/45 = 4x/15 boxes.
He had 60 boxes of mooncakes left, so 60 = (3x/5) - (4x/15).
Multiplying everything by 15 to get rid of the fractions, we get 900 = 9(3x) - 4(4x).
So, 900 = 27x - 16x.
Combining like terms, we get 900 = 11x.
Dividing both sides by 11, we get x = 900/11.
Thus, Baker Sam made x = 900/11 = 81.82 ~ <<81.82=81>>81 boxes of mooncakes.
Baker Sam gave 4x/15 = (4*81)/15 = 324/15 = 21.6 ~ 22 boxes of mooncakes to KK Home. Answer: \boxed{22}.
Baker sam mades some mooncakes and packed them equally into boxes. He gave 2 5 of the mooncakes to QQ Home and 4 9 of the remainder to KK Hom. He had 60 boxes of mooncakes left.
