A tennis player won 80% of his matches. If he played 50 matches, how many matches did he lose? (2023)

Step 1: Understand that the player won 80% of his matches.
Step 2: Calculate how many matches he won by finding 80% of 50 matches.
Step 3: To find 80% of 50, multiply 50 by 0.8 (which is the decimal form of 80%).
