Answer:
83.3%
Step-by-step explanation:
Games won: 80% of 15 plus 3 more: 12 + 3 = 15 games won out of 15 + 3 games played.
Percentage of matches won: 15/18 = 0.833333 ... → 83.3%
27
180
So you can get rid of the zero in the 20 for now and just solve 2 x 9, which is 18. Now you take the zero you got rid of earlier and put it at the end of 18 to get 180.
I hope this helps.
