What is the weight ratio?

I understand it this way: weight ratio: it is to weight important data. When calculating the weighted average, according to the actual needs,

Giving different types of data a proportion corresponding to their importance is to weight these data, and the weighted value is the weight ratio.

For example, when the company recruits public relations personnel, A scored 86 points in interview, 90 points in written test, with an average of 88 points, 92 points in interview and 83 points in written test, with an average of 87.5 points. A will be given priority. The company thinks that the interview results of public relations personnel should be more important than the written test results, and gives them 6 and 4 rights respectively, with a weight ratio of 6 and 4. Then find the weighted average: A[86×6+90×4]/[6+4]= 87.6 points, B[92×6+83×4]/[6+4]= 88.4, and select the best candidates through comparison.
