Anne and maria play tennis almost every weekend so far anne has won 12 out of 20 matches how many matches will anne have to win in a row to improve their winning percentage to 75%

12 more games.
The current winning percentage is 60%, which is found by dividing 12 by 20 and multiplying by 100 (12 / 20 = 0.60, 0.60 x 100 = 60).

To get a winning streak of 75%, Anne has to win 12 more games in a row. That will mean she will have won 24 out of a total of 32 matches, and this decimal is equal to 0.75. Multiply by 100 to get the percentage of 75%.

Anne would have to win 15 matches to get a 75%
