Question

Kiara has a new beaded necklace. 16 out of the 20 beads on the necklace are blue. What percentage of beads on Kiara's necklace are blue?

Write your answer using a percent sign (%).

Answer 1

To find the percentage of blue beads on Kiara's necklace, you can use the formula:

\[
\text{Percentage} = \left( \frac{\text{Number of blue beads}}{\text{Total number of beads}} \right) \times 100
\]

In this case, the number of blue beads is 16 and the total number of beads is 20. Plugging in the numbers:

\[
\text{Percentage} = \left( \frac{16}{20} \right) \times 100
\]

First, simplify \( \frac{16}{20} \):

\[
\frac{16}{20} = 0.8
\]

Now, multiply by 100 to convert it to a percentage:

\[
0.8 \times 100 = 80
\]

Thus, the percentage of beads on Kiara's necklace that are blue is

\[
\boxed{80\%}
\]
