The dolphins at the zoo eat 3 1/8 buckets of fish each day, the killer whale eat 2 3/5 times as much fish as the dolphins, how many buckets of fish do the whales eat each day

You could convert the decimal into a fraction, which will give you 65/8, which is an improper fraction. You can convert this fraction into a mixed number by dividing, and that would give you 8 1/8.

Answer:

The whales eat [tex]8\frac{1}{8}[/tex] buckets of fish per day.

Step-by-step explanation:

Givens:

Dolphins eat [tex]3\frac{1}{8}=\frac{25}{8}[/tex] buckets.
Killer whale eat [tex]2\frac{3}{5}=\frac{13}{5}[/tex] times as much fish as dolphins.

To answer the question, we need to express the problem with equations, [tex]D[/tex] is dolphins and [tex]W[/tex] is whale.

The killer whale eats:

[tex]W=\frac{13}{5}D[/tex]

But, [tex]D=\frac{25}{8}[/tex]

So, the killer whale eats:

[tex]W=\frac{13}{5}\frac{25}{8}=\frac{325}{40}=8\frac{1}{8}[/tex]

Therefore, the whales eat [tex]8\frac{1}{8}[/tex] buckets of fish per day.
