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

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.

The whales eat buckets of fish per day.

Step-by-step explanation:

Givens:

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

The killer whale eats:

But,

So, the killer whale eats:

Therefore, the whales eat buckets of fish per day.

the least common denominator is 40

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
