There is a math problem: a salesperson missed a decimal point, which increased the turnover by 2 1.42 yuan. What's the original number?
The decimal point is wrong, which makes the turnover increase, which can only be ten times or a hundred times, and so on. If it is 10 times, it is 9 times more, 2 1.42÷9=2.38, if it is 99 times, it is 2 1.42÷99 times, but this cannot be divided.
