Question

In 2019, a research institute reported the discovery of 71 new species, including 17 fish, 15 geckos, and 6 sea slugs. What percentage of the new species reported were not fish, geckos, or sea slugs? Round to the nearest tenth of a percent.

Answer 1

To find the percentage of new species that were not fish, geckos, or sea slugs, subtract the number of fish, geckos, and sea slugs from the total number of new species and calculate the percentage. The result is 46.5%.

Step-by-step explanation:

To find the percentage of new species that were not fish, geckos, or sea slugs, we need to subtract the total number of fish, geckos, and sea slugs from the total number of new species and then calculate the percentage. In this case:

Total new species = 71

Number of fish = 17

Number of geckos = 15

Number of sea slugs = 6

Number of new species that are not fish, geckos, or sea slugs = Total new species - Number of fish - Number of geckos - Number of sea slugs = 71 - 17 - 15 - 6 = 33

Percentage of new species that are not fish, geckos, or sea slugs = (Number of new species that are not fish, geckos, or sea slugs / Total new species) * 100 = (33 / 71) * 100 = 46.5% (rounded to the nearest tenth of a percent).
