Question

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

Answer 1

Answer:

In order to solve this you would have to multiply 3 1/8 by 2 3/5.

Step-by-step explanation:

3 1/8 * 2 3/5 = 8.125

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 2

Answer:

The whales eat $8\frac{1}{8}$ buckets of fish per day.

Step-by-step explanation:

Givens:

• Dolphins eat $3\frac{1}{8}=\frac{25}{8}$ buckets.
• Killer whale eat $2\frac{3}{5}=\frac{13}{5}$ times as much fish as dolphins.

To answer the question, we need to express the problem with equations, $D$ is dolphins and $W$ is whale.

The killer whale eats:

$W=\frac{13}{5}D$

But, $D=\frac{25}{8}$

So, the killer whale eats:

$W=\frac{13}{5}\frac{25}{8}=\frac{325}{40}=8\frac{1}{8}$

Therefore, the whales eat $8\frac{1}{8}$ buckets of fish per day.
