Answer 1

Answer:

Let the number of students be X

Then the girls =2X/9

Boys= 7x/9

7x/9=840

Rotal numer of students=840*9/7=1080

Girls=1080-840=240

Answer 2

Answer:

240 girls

Step-by-step explanation:

Let the total number of students be  x.

No: of boys = 840

7/9 of  x = 840

(7/9 )* x = 840

x = (840 * 9) / 7

x = 1080

No of girls = (2/9) of x =  (2/9) * 1080 =240
