If 80% are left handed, you can find the number of right handed people by subtracting 80% from the total of a percentage which is 100%
That will be;
100%-80%=20%
20% are right handed
So now you need to find how many people make up 20%. That will be;
20/100 x 90 (% means over 100 and 90 is the number of players)
That will give you 18. So 18 players are right handed
Answer is 18 players
Hope that helped. Have a nice day
