Answer:
Explanation:
Let's assume the number of guppies is x.
According to the problem, the number of tetras is 11 times the number of guppies, so we can represent the number of tetras as 11x.
Now, we can set up an equation to represent the total number of fish:
x + 11x = 48
Combining like terms, we have:
12x = 48
To solve for x, we divide both sides of the equation by 12:
x = 48/12
x = 4
Therefore, Hank has 4 guppies.
Now, we can find the number of tetras:
Number of tetras = 11 * Number of guppies
Number of tetras = 11 * 4
Number of tetras = 44
Therefore, Hank has 4 guppies and 44 tetras in his aquarium.
