Elmer has a collection of 300 fossils. Of these, 21% are fossilized snail shells. How many fossilized snail shells does Elmer have? fossilized snail shells

Convert percentage to decimal: Write 21% as a decimal. 21% = 21/100 = 0.21Identify expression for number of fossilized snail shells: We know: • Total number of fossils: 300 • 21% is equivalent to 0.21 Identify the expression for the number of fossilized snail shells. Percent * Whole = Part Percent of fossilized snail shells * Total number of fossils = Number of fossilized snail shells 0.21 * 300 represents the number of fossilized snail shells.Calculate number of fossilized snail shells: We found: Number of fossilized snail shells = 0.21 * 300. Simplify 0.21 * 300. 0.21 * 300 = 63 There are 63 fossilized snail shells in Elmer's collection.

How many fossilized snail shells does Elmer have?

\newline

fossilized snail shells

Convert percentage to decimal: Write $21\%$ as a decimal. $21\% = \frac{21}{100} = 0.21$
Identify expression for number of fossilized snail shells: We know: $\newline$ • Total number of fossils: $300$ $\newline$ • $21\%$ is equivalent to $0.21$ $\newline$ Identify the expression for the number of fossilized snail shells. $\newline$ $\text{Percent} \times \text{Whole} = \text{Part}$ $\newline$ $\text{Percent of fossilized snail shells} \times \text{Total number of fossils} = \text{Number of fossilized snail shells}$ $\newline$ $0.21 \times 300$ represents the number of fossilized snail shells.
Calculate number of fossilized snail shells: We found: Number of fossilized snail shells = $0.21 \times 300$ . Simplify $0.21 \times 300$ . $0.21 \times 300 = 63$ There are $63$ fossilized snail shells in Elmer's collection.
