Before Huanggang Gold Medal Olympic Mathematics School, female teachers accounted for 4/5 of the teachers in the whole school, and then three male teachers were recruited.

Test center: practical application of percentage topic: analysis of the application of percentage: three female teachers were transferred and three male teachers were transferred, and the total number of teachers remained unchanged. Taking the total number of teachers as the unit "1", the original number of female teachers was 60%, so the number of male teachers was 40%. Now the number of male teachers is 44%, which is an increase (44%-40%). Then find out what percentage of female teachers accounts for the total number, and then find out what percentage of female teachers is more than male teachers, and then multiply this percentage by the total number. 44%-( 1-60%), =44%-40%, = 4%; 3÷4%=75 (person); 75×( 1-44%-44%), =75× 12%, =9 (person); A: At present, there are 9 more female teachers than male teachers. So I choose: A. Comments: To solve this problem, find a constant and take it as the unit "1". What is the percentage of the known unit "1"? Find the unit "1"by division; Find the percentage of the unit "1" by multiplication.
