Answer 1

Answer: The killer whales eat $8\dfrac18$ buckets each day.

Step-by-step explanation:

GIven: Dolphins eat $3\dfrac18$ fish each day.

Since, $3\dfrac18 =\dfrac{25}{8}$

The killer whales eat $2\dfrac35$  times as much fish as the dolphins.

Since, $2\dfrac35=\dfrac{5(2)+3}{5}=\dfrac{10+3}{5}=\dfrac{13}{5}$

The number of buckets of fish, the killer whales eat each day $=\dfrac{25}{8}\times\dfrac{13}{5}$

$=\dfrac{5}{8}\times\dfrac{13}{1}=\dfrac{65}{8}$

$=8\dfrac18$

The killer whales eat $8\dfrac18$ buckets each day.
