197 students (rounded to the nearest whole number)

Step-by-step explanation:

first I divided 11 by 114 to find out how much girls there are to every one boy and my answer was 10.36 (rounded to the nearest 2 d.p).

next I times it by eight according to the ratio given, my answer was 83 (rounded to the nearest whole number)

finally, I just added 114 and 83 together to get the total number of students and my answer to that was 197 (rounded to the nearest whole number)
