The application problem has no conversion unit, so it will not be judged according to the calculation error. Write a solution for one point and give two points for the correct formula. It is completely wrong to receive your question, and no points will be given. If the result is correct, you can get one point by writing the solution, and if the result is correct, it is also one point. No, like this exam, the score is only one point. Moreover, the teacher will tell the students to write the solution whether they like it or not, so that they can also score.
