Question

The dolphins at the San Diego zoo eat 3 1/8, start fraction, 1, divided by, 8, end fraction buckets of fish each day. The killer whales eat 2 3/5 ​ 2, start fraction, 3, divided by, 5, end fraction times as much fish as the dolphins. How many buckets of fish do the killer whales eat each day?

Answer 1

Answer: The killer whales eat
`8\frac18` buckets each day.

Explanation:

GIven: Dolphins eat
`3\frac18` fish each day.

Since,
`3\frac18 =(25)/(8)`

The killer whales eat
`2\frac35` times as much fish as the dolphins.

Since,
`2\frac35=(5(2)+3)/(5)=(10+3)/(5)=(13)/(5)`

The number of buckets of fish, the killer whales eat each day
`=(25)/(8)*(13)/(5)`

`=(5)/(8)*(13)/(1)=(65)/(8)`

`=8\frac18`

The killer whales eat
`8\frac18` buckets each day.
