<think>Start by identifying what is the best multiplication or combination of operations to close in on 192. We quickly see that (78 ÷ 4) gives you an integer close to 192, but this loses precision. Next, we use the other options to fine-tune this result. Hopefully, by then subtracting and dividing correctly resulted in 192. Show your work in <think> </think> tags. And return the final equation and meaning in <answer> </answer> tags.<|im_end|>
