Answer:

It's already a rational number?

Step-by-step explanation:

A rational number is any number that can be written as a fraction/ratio, and $2\frac{5}{8}$ is certainly a fraction. If you meant $2\frac{5}{8}$ as a decimal, then it'd be 2.625.

an aquarium has a ratio of 5 rays for every 3 sharks. What percent of this grouping of animals are rays

Answer:

62.5%

Step-by-step explanation:

Total number of animals in a group= 5+3=8 animals

Number of rays=5

Since we only have 5 rays out of the total 8, to express the number of rays as a percentage of the total animals, we divide the number of rays by the total animals then multiply by 100 to express in percentage as needed in the question

Percentage of rays= $\frac {5}{8}\times 100=62.5$
