75 1/3 = 75.33
75.33% = 75.33/100
= 7533/10000
not sure if it can be simplified more than this
Answer:
x=# of boys
x+7=# of girls
x+x+7=25
2x+7=25
2x=25-7
2x=18
x=18/2
x=9 boys
x+7=16 girls
If you don't understand variables use trial and error.
Boys Girls
1 8
2 9
3 10
4 11
5 12
6 13
7 14
8 15
9 16 9+16=25 students
You could start this way...
Boys Girls
12 13
11 14
10 15
9 16 16 is 7 more than 9
The answer would be C)3-x/x(x-1)
X=15
Hope this helps I had the same problem. That’s what I got.
