Answer with Step-by-step explanation:
We are given that:
Sean purchased a new fish tank. He bought 7 guppies, 12 cichlids, 4 tetras, 9 corydoras and 2 synodontis catfishes.
1) what is the ratio of guppies to cichlids?
number of guppies=7
number of cichlids=12
Ratio of guppies to cichlids=7:12
2) what is the ratio of tetras to catfishes?
number of tetras=4
number of catfishes=2
Ratio of tetras to catfishes=4:2=2:1
3) what is the ratio of corydoras catfishes to the total number of fish?
number of corydoras=9
total fishes=7+12+4+9+2=34
Ratio of corydoras catfishes to the total number of fish=9:34
