Q. Elmer has a collection of 300300 fossils. Of these, 21% 21 \% are fossilized snail shells.\newlineHow many fossilized snail shells does Elmer have?\newlinefossilized snail shells
  1. Convert percentage to decimal: Write 21%21\% as a decimal.21%=21100=0.2121\% = \frac{21}{100} = 0.21
  2. Identify expression for number of fossilized snail shells: We know:\newline• Total number of fossils: 300300\newline• 21%21\% is equivalent to 0.210.21\newlineIdentify the expression for the number of fossilized snail shells.\newlinePercent×Whole=Part\text{Percent} \times \text{Whole} = \text{Part}\newlinePercent of fossilized snail shells×Total number of fossils=Number of fossilized snail shells\text{Percent of fossilized snail shells} \times \text{Total number of fossils} = \text{Number of fossilized snail shells}\newline0.21×3000.21 \times 300 represents the number of fossilized snail shells.
  3. Calculate number of fossilized snail shells: We found: Number of fossilized snail shells = 0.21×3000.21 \times 300. Simplify 0.21×3000.21 \times 300. 0.21×300=630.21 \times 300 = 63 There are 6363 fossilized snail shells in Elmer's collection.
