Answer:

Step-by-step explanation:

Percentage of Silver fishes in the aquarium = 35 %

Given :There are 500 fishes in an aquarium.

The number of gold fishes is 145. The number of blue fishes is 180. Remaining are the silver fishes.

To Find :The percentage of silver fishes in the aquarium.

Step By Step Explanation :It is given that in a aquarium there are 500 fishes out of which 145 are gold fishes, 180 are blue fishes and remaining are silver fishes. We need to find the percentage of silver fishes in the aquarium. Let's do it

!!Number of Silver fishes =

Total number of fishes - ( number of Gold fishes + number of Blue fishes )Number of Silver fishes =

500 - ( 145 + 180 )= 500 - 325 => 175.Now, Percentage of Silver fishes will be ⤵$\boxed{\sf{\red{\cfrac{Number\:of\:Silver\:Fishes} {Total\:Number\:of\:Fishes} \times100}}}$By substituting the values$\longmapsto\sf\cfrac{\cancel{175}}{ \cancel{500}} \times \cancel {100} \\ \\ \longmapsto \sf35\%$Therefore the percentage of silver fishes in the aquarium is 35 %__________________________

Answer 2

Answer:

c = 4.35 =  4 whole (7/20)

Step-by-step explanation:

20 = (19/4) + (37/6) + (27/5) + c

20 = (245 + 370 + 324 + 60c)/60

1200 = 939 + 60c

261 = 60c

c = (87/20) = 4 whole (7/20)
