Using the numbers [27, 48, 53, 7], create an equation that equals 65. You can use basic arithmetic operations (+, -, *, /) and each number can only be used once. Provide your solution in the form of an equation in <think> </think>, and present the final result in your answer, formatted as <answer> </answer>. For example, if you solve the equation as <think>27*48 / (53 - 7) = 65</think>, your solution would look like <answer>27*48 / (53 - 7) = 65</answer>. Remember that each number must be used exactly once!<|im_end|>
