In order to overlook someone's faults, it takes love and an understanding that you are not perfect.
When you love someone, you tend not to see that person's flaws, or even if you do see them, you believe those flaws are negligible. Once you understand that you yourself are not perfect (as any other human being), it will be easier for you to overlook someone else's faults.
SO from what I did was...
Since 24 x 3 = 72 , I did the same to 16.
16 x 3 = 48
But because instead of their being 3 teachers there is 1... What I did is just was to divide 48 / 2 which gave me the answer of 24...
So what I think the answer is...
There are 72 boys, 24 girls, and 1 teacher...
Unless I am just dumb and it would be 48 girls, but I think I did it right.
I hope I was able to help out.
