Just got a little confused and I am perhaps thinking a little slow today. But just wanted to ask what is the correct way to calculate fractions. I am going through this tutorial

- You have 53,2 shares issued and the overallotment percentage is 15%, meaning it should be 15% of those 53,2 shares.
- In a tutorial I am going through here they calculate this as 53,2/(1+0,15) = 6,9. However, if you divide 6,9/53,2 you get to 13%… Why does he not take 0,15*53,2 to arrive at 8m shares?

Which way is correct?
