Answer:
3 more matches.
Step-by-step explanation:
We can check the percentage by dividing them.
Example: If she won 12/20 then,
12÷20=.6
Turn decimal into percentage,
=60%
So far, her percentage is 60% since she has won 12 out of 20.
In order to get the 75%, we need to find to have a 3/4.
So to make it 3/4, she needs to win 3 more matches to make it 15/20.
How come 15/20 is 3/4? It's because if you divide both of them with 5, it will come up with 3/4.
3÷4 or 15÷20, the answer will still be . 75 or 75%.
