Q. Of all the species in the world, 44 out of every 55 are insects. What percent of species are insects?\newline(Ignore the % \% symbol when entering your answer. For example, if the answer is 11% 11 \% , enter 1111 .)
  1. Given information: We have: \newlineTotal number of species categories: 55 \newlineNumber of species categories that are insects: 44 \newlineChoose the formula to find the percentage of species that are insects. \newlinePercentage formula: \newlineNumber of insect species categoriesTotal number of species categories×100\frac{\text{Number of insect species categories}}{\text{Total number of species categories}} \times 100
  2. Formula for finding percentage: Substitute the given numbers into the formula: (45)×100(\frac{4}{5}) \times 100
  3. Substituting the given numbers: Simplify 45\frac{4}{5} to get a decimal. \newline45=0.8\frac{4}{5} = 0.8
  4. Simplifying the fraction: Multiply the decimal by 100100 to find the percentage. \newline0.8×100=800.8 \times 100 = 80
