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).

Input: Consider Input: Two letters picked without replacement from gueugfuwu. Give prob of sequence wg.

Output: 1/36


Input: Consider Input: Suppose g + x - 9 = 0, -30 = -5*g + x - 9. Solve 4 - 9 = -g*h for h.

Output: 1


Input: Consider Input: Suppose l + 0*p + 21 = 5*p, 0 = -4*l - p + 21. Solve -4*f = -0*f - l*w + 4, 0 = -2*f - 5*w - 16 for f.


Output: -3
