(1) The number of winners is 240X3/5= 144.

(2) The number of winners of the first prize is (240x3/5) x1/6 = 240x (3/5x1/6) = 240x3/30 = 240x1/kloc-0 = 24.

Checking calculation: 24/240 =110

I can't figure out the logic. You can look at the simplification process of the formula in (2). I have shown several parts of the source code in bold. I don't know how to answer the questions in primary school.
