Answer:

Carlotta needs 24 orange beads for her necklace.

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:


(2)/(5)=(x)/(60)


5x=120

x=24

Hence, Carlotta needs 24 orange beads for her necklace.

Blue beads needed =
60-24=36

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


(36)/(24)

Divide by 4, we get


(9)/(6)

Divide by 3, we get


(3)/(2) ...... (the given ratio)

Therefore, Carlotta needs 24 orange beads for her necklace.
