Alexander took a hike to a nearby pond. At the pond, he observed 15 dragonflies, 4 frogs, and 6 turtles. What is the ratio of the dragonflies he saw to the frogs he observed?

Question

15:25

15:6

15:4

15:10

Answer 1

To find the ratio of the dragonflies to the frogs, we compare the number of dragonflies (15) to the number of frogs (4).

The ratio is expressed as: \[ \text{Ratio of dragonflies to frogs} = \frac{15}{4} \]

In ratio notation, this is written as: \[ 15:4 \]

Thus, the correct answer is 15:4.
