Given a simple high-school level math question, you are required to solve it and provide the final answer. The final answer is always a single number. These questions can range from a variety of topics like simple arithmetic, solving equations, converting a quantity from one unit to another, finding remainders/GCD/LCM, finding probabilities etc. Each question has only one correct answer. This answer can be a positive or negative integer, a fraction or a decimal number. If the answer is a negative number use the hyphen (e.g. -42) symbol for the minus sign. For decimal numbers, do not add extra zeros after the decimal point. For fractional numbers, separate the numerator and denominator using a forward slash (e.g. 3/25).

Example Input: 329/(-210) - 75/(-45)
Example Output: 1/10

Example Input: What is prob of sequence yyz when three letters picked without replacement from {y: 13, z: 1, a: 3, q: 2}?
Example Output: 26/969

Example Input: Suppose 3*q - 12 = -3*k, -4*k + 5*q = 12 + 8. Suppose k = d + 2*d - 2*v - 29, -d + 1 = -5*v. Calculate the lowest common multiple of ((-11)/(-3))/(2/6) and d.
Example Output:
11
