Problem: what is difference between biggest and smallest fraction among 1 / 3 , 3 / 4 , 4 / 5 and 5 / 6
Rationale: "explanation : 1 / 3 = . 33 , 3 / 4 = . 75 , 4 / 5 = . 8 and 5 / 6 = . 833 so biggest is 5 / 6 and smallest is 1 / 3 their difference is 5 / 6 - 1 / 3 = 3 / 6 = 1 / 2 option b"
annotated_formula: subtract(divide(4, 5), divide(1, 3))
