Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
At the aquarium, there are twice as many sharks as stingrays. If there are 28 stingrays, how many fish are there?

### Response:
 Ikiwa papa ni mara mbili ya nyangumi, na idadi ya nyangumi ni 28, basi idadi ya papa katika aquarium ni 2*28 = <<2*28=56>>56
Idadi ya samaki katika tangi ni 28+56 = <<28+56=84>>84
