Question

a zoo has 72 animals. 18 are birds and another 17 are reptiles. how many of the zoo animals are not birds or reptiles?
29
35
37
27

Explanation:

Step1: Find total birds and reptiles

To find the number of animals that are birds or reptiles, we add the number of birds and reptiles. So we calculate \(18 + 17\).
\(18+17 = 35\)

Step2: Subtract from total animals

To find the number of animals that are not birds or reptiles, we subtract the number of birds and reptiles from the total number of animals. The total number of animals is 72, so we calculate \(72-35\).
\(72 - 35=37\)

Answer:

37
