Question

Carlotta is making blue and orange necklaces in several lengths. For each necklace, her ratio of blue beads to orange beads is 3 to 2. How many orange beads will Carlotta need for a necklace of 60 beads?

Answer 1

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:

$\frac{2}{5}=\frac{x}{60}$

$5x=120$

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:

$\frac{36}{24}$

Divide by 4, we get

$\frac{9}{6}$

Divide by 3, we get

$\frac{3}{2}$  ...... (the given ratio)

Therefore, Carlotta needs 24 orange beads for her necklace.

Answer 2

5x=60 
x=12
2x=24
