Question

A tennis team has won 15 out of 20 matches they played this season. How many more matches will they need to win in a row to raise its winning percentage to 90%?

Answer 1

Answer:

they will need to win 18/20 matches

Step-by-step explanation:

if winning 9/10 matches gives them a winning percentage of 90% then you take 9/10 and multiple it by 2 since they played two times the matches of 10, then you get 18/20
