Answer:
5:6
Explanation:
Given the total number of games played by the softball team = 18 games
Total games won = 15 games
Ratio of the softball team's wins to its total number of games played can be gotten by simply dividing the total games won by the total games played
Ratio =
![(total \ teams's win)/(total\ number\ of \ games\ played)](https://img.qammunity.org/2021/formulas/mathematics/high-school/nfzhzvrms00kck9l4zlryk5634qm2rigeu.png)
![Ratio = (15)/(18)](https://img.qammunity.org/2021/formulas/mathematics/high-school/dm0pvk9u52ikl3gsp9xxlmgzmmbxbtzdz4.png)
Expressing the ratio in its lowest term
![Ratio = (3*5)/(3*6) \\\\Ratio = (5)/(6)](https://img.qammunity.org/2021/formulas/mathematics/high-school/m82op8s705gtjydjywp2yfc5quigwlj1io.png)
Hence, the ratio of the softball team's wins to its total number of games played is 5:6
