Problem: determine the value of 3 * 27 / 31 + 81 / 93
Rationale: solution : both fractions should be reduced before performing arithmetic operations . we get 3 * 27 / 31 + 3.27 / 3.31 = 3 * 27 / 31 + 27 / 31 = 4 * 27 / 31 = 151 / 31 answer d
annotated_formula: divide(add(subtract(add(81, multiply(27, 3)), subtract(93, 81)), const_1), 31)
