Question

Tammy has a jewelers bag with 225 beads to make bracelets. the ratio of blue beads to silver beads is 7:8. how many blue beads are in the bag

Answer 1

To find the number of blue beads, the total beads are divided by the sum of the ratio parts and then multiplied by the blue ratio part, resulting in 105 blue beads in the bag.

Step-by-step explanation:

The question is asking us to find out how many blue beads are in the bag given a total of 225 beads and the ratio of blue beads to silver beads is 7:8. To solve this, we must first determine the total number of parts in the ratio. Since the ratio is 7 blue beads for every 8 silver beads, there are 7 + 8 = 15 parts in total.

Now we can calculate the value of each part by dividing the total number of beads by the total number of parts in the ratio:

1. Divide 225 beads by 15 parts: 225 ÷ 15 = 15 beads per part.
2. Multiply the result by the number of parts for blue beads: 15 beads per part × 7 parts = 105 blue beads.

Therefore, Tammy has 105 blue beads in her bag.
