on a soccer team, 5 out of 13 players surveyed say they had two or more siblings, the league has 520 players which answer is the best prediction of the number of players in the league that have two or more siblings
5 over 13 to x over 520 as 13 was the total and the current is now 520. In order to find the new conversion, multiply 5 and 520 and divide by 13 which would give you 330.
I’m pretty sure this is correct and I hope it helps!
