Answer:

Carlotta needs 24 orange beads for her necklace.

Step-by-step explanation:

For each necklace, the ratio of blue beads to orange beads is 3 to 2. or 3:2

Total beads given to make a necklace is = 60

Let the number of orange beads be = x

The ratio is 2 orange beads out of 5 total beads

So, we can represent the ratio as:

[tex]\frac{2}{5}=\frac{x}{60}[/tex]

[tex]5x=120[/tex]

x=24

Hence, Carlotta needs 24 orange beads for her necklace.

Blue beads needed = [tex]60-24=36[/tex]

We can also check the ratio for blue beads to orange beads:

[tex]\frac{36}{24}[/tex]

Divide by 4, we get

[tex]\frac{9}{6}[/tex]

Divide by 3, we get

[tex]\frac{3}{2}[/tex]  ...... (the given ratio)

Therefore, Carlotta needs 24 orange beads for her necklace.
