This could be a diagram.
To solve this problem using a bar diagram, you can follow these steps:
Step 1: Understand the problem
We have a ratio of 1 coach for every 12 players. We need to find out how many coaches we will need for 48 volleyball players.
Step 2: Set up the bar diagram
Draw a bar diagram with two bars representing coaches and players. Label the bars accordingly.
Step 3: Determine the relationships
Since the ratio is 1 coach to 12 players, we can determine the proportion of the bars. If one bar represents 12 players, divide the coaches' bar into 12 equal parts since each part represents one player.
Step 4: Represent the given information
Now, in the players' bar, draw 48 equal parts to represent the 48 players you need to account for.
Step 5: Count the coaches
Count how many equal parts the coaches' bar is divided into. Each part represents one player, so if you count the parts that encompass the 48 players in the players' bar, you will get the number of coaches needed.
In this case, as you mentioned, the answer is four coaches. So, you will need to count four equal parts in the coaches' bar that represents the 48 players.
Although it is difficult to draw a bar diagram here, following these steps will help you visualize and understand the concept visually.
