Answer:the ratio of hamsters to other animals in the pet shop = 4: 1
Step-by-step explanation:
Step 1
Let Total number of animals in the shop = 1 ( since we are dealing with fraction)
Number of hamsters= 4/5
Number of other animals = Total Number of animals in the pet shop - Number of hamsters
= 1-4/5
=5/5-4/5 =1/5
Step 2---Ratio of hamsters to other animals
Hamster : Other Animals
4/5 :1/5
4/5 / 1/5 : 1/5 / 1/5
4/5 x 5/1 : 1/5 x 5/1
=4:1
or
4/5: 1/5
0.8 : 0.2
0.8/0.2 : 0.2/0.2
4 : 1
