Final answer:
To find the total number of matches played, set up a proportion to solve for the unknown variable x. The total number of matches played is 25.
Step-by-step explanation:
To find the total number of matches played, we can use the idea of proportions. We know that the team won 15 matches, which is 60% of the total. Let's represent the total number of matches as 'x'. We can set up the proportion: 15/ x = 60/100. Cross-multiplying, we get 60x = 15 * 100. Solving for x, we find that the total number of matches played in all is 25.
