Question

There are about 4.5 × 10⁷ dogs living on Earth right now, and about 2 × 10⁵ wolves. How many dogs are there per wolf on Earth (i.e., the ratio of dogs to wolves)?"

A) 225
B) 22.5
C) 2,250
D) 225,000

Answer 1

To calculate the ratio of dogs to wolves on Earth, you divide the number of dogs (4.5 x 10⁷) by the number of wolves (2 x 10⁵), resulting in a ratio of 2250.

Step-by-step explanation:

To calculate the ratio of dogs to wolves on Earth, we divide the total number of dogs by the total number of wolves:

1. Number of dogs: 4.5 × 10⁷
2. Number of wolves: 2 × 10⁵
3. Ratio = Number of dogs / Number of wolves
4. Ratio = (4.5 × 10⁷) / (2 × 10⁵)
5. Ratio = 4.5 / 0.002 × 10²
6. Ratio = 2250

Therefore, the ratio of dogs to wolves is 2250:
