Question 244584: If the ratio of boys to girls in a class is 3 to 8, will the ratio of boys to girls stay the same, become greater or become lesser if 2 boys and 2 girls leave the class. Justify your answer.
This is what I answered, I just don't think it is correct:
The ratio will stay the same because you are removing the same amount of both girls and boys out of the class. Therefore, the ratio doesn't change because even though it diminishes the class by 4 students, the proportion of boys to girls doesn't change.

You can put this solution on YOUR website! Unfortunately, that is incorrect. Let's say we have a simple example of 3 boys and 8 girls. So the ratio of boys to girls is 3 to 8. Now take 2 boys and girls away to get 1 boy and 6 girls. So the ratio is now 1 to 6, which is NOT equivalent to the ratio of 3 to 8. Try other values such as 6 boys and 16 girls and you'll find that the ratio does change.
