1. In language school , 475/12 %of the students learn chinese ,125/4 % of the student learn German and the remaining 210 student learn Japanese .
What is the total number of student ?
Do you mean that 475 learn Chinese and that is 12% of the total student body?
Or do you mean 475/12% = 39.58% study Chinese?
If that is what you mean, then
125/4 % = 31.25%
Since Japanese is the only remaining language studied, then 29.17% study Japanese. This assumes that all students study only one language.
0.2917 N = 210. N = 720
