Regular filling: 3 / 20, 5 / 34, 8 / 55, 12 / 83 Fill in: 3 / 20, 5 / 34, 8 / 55, 12 / 83, (/) I hope the answer is not 118 / 17 I can see that the price of each item is 0.15

3 / 20 is (20 + 1) / 3 = 7
5/34,(34+1)/5=7
8/55,(55+1)/8=7
12/83 (83+1)/12=7
The rule is (denominator + 1) / numerator = 7
So the answer is 17 / 118
