Question

The ratio of the number of snakes to the number of lizards in a reptile zoo is 3:7. What fraction of the total animals at the reptile zoo are lizards?

Answer 1

The fraction of the total animals that are lizards at the reptile zoo, given the ratio 3:7 for snakes to lizards, is 7/10.

Step-by-step explanation:

According to the given ratio, there are 3 parts snakes and 7 parts lizards, making a total of 10 parts.

To determine what fraction of the total animals are lizards, we divide the number of parts that are lizards by the total number of parts.

To calculate the fraction of lizards, we have:

1. Number of parts for lizards: 7
2. Total number of parts (snakes + lizards): 3 (snakes) + 7 (lizards) = 10
3. Fraction of lizards: 7/10

Therefore, the fraction of the total animals that are lizards is 7/10.
