Answer:

g/15 = 100/115 so g = 13

Step-by-step explanation:

a 15 percent increase means that there is now 115% of what there was last time. normally its 100% so the ratio is 100:115 and the ratio of gorls is g:15. since the ratios are equal multiply 100/115 by 15 to get g so 13

Answer:

13 grls in ur class

Step-by-step explanation:

15*115%=17

17-15=2
