Final answer:
To find the number of bluegills caught, use the ratio of bluegills to sunfish and solve for bluegills, which results in 6 bluegills.
Step-by-step explanation:
To find the number of bluegills caught, we need to determine the ratio between bluegills and sunfish. The ratio is given as 2 bluegills for every 5 sunfish. If the scouts caught 15 sunfish, we can use this ratio to find the number of bluegills:
2 bluegills / 5 sunfish = x bluegills / 15 sunfish
Cross-multiplying, we get:
5x = 2 * 15
5x = 30
x = 30 / 5
x = 6
Therefore, the scouts caught 6 bluegills.
