Answer 2

Answer:

Sharon bought a necklace with 90% blue beads.

Step-by-step explanation:

We are given that Sharon's necklace has 80 beads. We are also given that of those 80 beads, 72 of them are blue.

Therefore, we can set up a ratio of blue beads to total beads in order to find out the relationship.

$\displaystyle \frac{72}{80}=\frac{36}{40}=\frac{18}{20}=\frac{9}{10}$

Then, using the fraction we receive as a result, we can convert this to a decimal.

$\displaystyle \frac{9}{10} = 0.9$

After we complete this calculation, we can multiply our decimal by 100 in order to obtain the relationship in percentage form.

$0.9 \times 100 = 90\%$

Of the 80 beads, 90% were blue beads.
