katrin [286]

Answer:

44200 of them were girls

Step-by-step explanation:

If the ratio is 8:25, we must find x:65000

In order to change the ratio 8:25 into x:65000, we must multiply 25 by 2600. So you have to multiply 8 by 2600 too

8 x 2600 = 20800

65000 (total students) - 20800 (boy students) = 44200 (girl students)
