hank has 48 fish in his aquarium. he has 11 times as many tetras as guppies. how many of each type of dis does hank have?
that is like the ratio Tetra: ruppies
that is 11:1
so add them together thta is 12=
12x11 tetras is 44
4x1 guppies=4
44:4
Guppies . . . . 1 time
Tetras . . . . . 11 times
Sum of fish. . . . . 12 times
Number of fish . . 48
12 times = 48
Divide each side of the equation by 12 :
1 time = 4
Guppies = 1 time = 4 guppies
Tetras = 11 times = 11 x 4 = 44 tetras
Total fish = 4 + 44 = 48 yay !
