Question

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

Answer 1

Number of buckets of fish eaten by killer whales is $\frac{65}{8}$ or $8\frac{1}{8}$

Solution:

Given that dolphins at the San Diego zoo eat $3\frac{1}{8}$ buckets of fish each day

Number of buckets of fish eaten by Dolphins = $3\frac{1}{8} = \frac{3 \times 8 + 1}{8} = \frac{25}{8}$

Also given that killer whales eat $2\frac{3}{5}$ times as much fish as the dolphins.

Which means number of fishes eaten by killer whales is $2\frac{3}{5}$ multiplied by number of fishes eaten by dolphins

So number of fish eaten by killer is:

$\text {number of fish eaten by killer }=2 \frac{3}{5} \times \text { number of fish eaten by dolphins }$

$\text {number of fish eaten by killer }=2 \frac{3}{5} \times \frac{25}{8}=\frac{13}{5} \times \frac{25}{8}=\frac{65}{8}$

Thus the number of buckets of fish eaten by killer whales is $\frac{65}{8}$ or $8\frac{1}{8}$

Answer 2

Answer:

8 5/40

Step-by-step explanation:

1 = 8/8

3 = 24/8.

24+1 = 25

2 = 10/5

10+3 = 13

5*8 = 40

25*13 = 250 + 75 = 325

325/40 = 8 5/40
