Let T be the total number of pieces of fruit.
Let R be the number of rotten pieces of fruit.
number of watermelons: 0.13T
number of apples: 0.69T
number of rotten watermelons: 0.52R
number of rotten apples: 0.24R
chance of rotten watermelon: 0.52R/0.13T
chance of rotten apple: 0.24R/0.69T
answer:
0.52R/0.13T / 0.24R/0.69T
= 0.52R/0.13T * 0.69T/0.24R
= 0.52/0.13 * 0.69/0.24
= 11.5
