4/5 of the animals in a pet shop are hamsters. What is the ratio of hamsters to other animals in the pet shop in its simplest
form?

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

is there answer choices?
