There is x sugar.

X candies are distributed to five people, four to four people, three to three people, and there are two left.

That X+ 1 candy is distributed to five people on average, five to four people stay on average, four to three people stay on average, and three.

That is, x+ 1 is a common multiple of 3, 4 and 5.

The least common multiple of 3, 4 and 5 is 3*4*5=60.

So X=60- 1=59.

2、56/ 105=8/ 15
