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

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

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

The whales eat
`8(1)/(8)` buckets of fish per day.

Explanation:

Givens:

• Dolphins eat
  `3(1)/(8)=(25)/(8)` buckets.
• Killer whale eat
  `2(3)/(5)=(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=(13)/(5)D`

But,
`D=(25)/(8)`

So, the killer whale eats:

`W=(13)/(5)(25)/(8)=(325)/(40)=8(1)/(8)`

Therefore, the whales eat
`8(1)/(8)` buckets of fish per day.
