Okay, imagine you have some candy bars that you want to share with your friends. You have 8 candy bars in total, but you want to make sure that everyone gets a fair share.
Now, let's say you have 4 friends over, so there are 5 of you altogether. To be fair, you need to divide the candy bars equally among everyone. When you do the math, you realize that each person should get 1 1/2 candy bars (that's one and a half candy bars).
The v2 ratio is a way of expressing this type of division or sharing. It is a ratio that compares the size of two quantities, but it also takes into account how many parts those quantities are being divided into. In our example, the v2 ratio is 8:5 because we have 8 candy bars and 5 people.
To calculate the v2 ratio, you need to square the number of parts that you are dividing the quantities into. In our example, we have 5 people, so we square that number to get 25. Then we divide the total quantity (8) by the squared number (25) to get the v2 ratio.
So, the v2 ratio for our candy bar example is 8:25. This means that each person should get 8/25 of a candy bar. If we multiply that fraction by 5 (for the number of people), we get 2 candy bars in total, which is exactly what we started with.
So, the v2 ratio helps us divide things up fairly by taking into account the number of parts we are dividing the quantities into. Pretty cool, huh?
