A study found that 27% of the fish in a river are trout, 36% are salmon, and 18% are sturgeon. If a large fish trap is set and it captures 216 fish, how many of those fish are likely to be fish types other than the ones mentioned?
To find out the number of fish types other than trout, salmon, and sturgeon, we need to calculate the percentage of fish not accounted for by these three types.
The total percentage of fish types mentioned (trout, salmon, and sturgeon) is 27% + 36% + 18% = 81%.
To find the percentage of fish types other than the ones mentioned, we subtract this from 100%:
100% - 81% = 19%.
Next, we calculate the number of fish that are likely to be other types. We do this by multiplying the total number of fish captured by the percentage of other fish types:
19% / 100% * 216 = 0.19 * 216 = 41.04
Therefore, it is likely that 41 fish are types other than trout, salmon, and sturgeon.
To solve this problem, we first need to determine the percentages of fish that are not trout, salmon, or sturgeon. Since the percentages of these three fish types are given as 27%, 36%, and 18% respectively, we can find the percentage of fish that are "other" by subtracting these three percentages from 100%.
First, let's calculate the percentage of fish that are not trout:
100% - 27% = 73%
Next, let's calculate the percentage of fish that are not salmon:
100% - 36% = 64%
Finally, let's calculate the percentage of fish that are not sturgeon:
100% - 18% = 82%
Now, we have the percentages of fish other than trout, salmon, and sturgeon as 73%, 64%, and 82% respectively.
To find the number of fish that are likely to be other fish types, we need to multiply these percentages by the total number of fish captured by the trap, which is 216.
Number of fish likely to be other than trout = (73/100) * 216 = 157.68 approximately 158 fish
Number of fish likely to be other than salmon = (64/100) * 216 = 138.24 approximately 138 fish
Number of fish likely to be other than sturgeon = (82/100) * 216 = 177.12 approximately 177 fish
Therefore, the total number of fish likely to be other fish types is approximately 158 + 138 + 177 = 473 fish.
27 + 36 + 18 = 81%
100 - 81 = 19% are not those fish
0.19 * 216 = ?
