Question

Arlene makes a necklace using 14 purple beads for every 6 silver beads. The necklace contains 18 beads. How many of each color bead are in the necklace?

Answer 1

Answer:

5.4 numbers of purple beads and 12.6 numbers of silver beads.

Step-by-step explanation:

Arlene makes a necklace using 14 purple beads for every 6 silver beads. So, she uses purple and silver beads in the ratio 14 : 6 = 7 : 3.

Now, the necklace contains 18 beads, then in the ratio 7 : 3, there will be $(18 \times \frac{3}{3 + 7}) = 5.4$ numbers of purple beads and (18 - 5.4) = 12.6 numbers of silver beads. (Answer)
