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: Evaluate (-1)/4 - (-6 - (-188)/32).
Example Output: -1/8

Example Input: Convert 343372.3cm to meters.
Example Output: 3433.723

Example Input: Let m(p) = 4*p - 6. Let j be m(5). Let k = j - 9. Suppose -4*u - k*b = -135, -2*u = -0*u + 4*b - 66. Calculate the greatest common divisor of u and 7.
Example Output:
7
