Janine wants a necklace that is 45 beads long. How many red and blue beads does she need if the ratio is 1:4?

If there are 45 beads, with a ratio of 1 : 4 Then, 5 45 ​ = 9 Then if 4 1 ​ = x 9 ​ Then x = 9 ∗ 4 Therefore, x = 36 Meaning, there would be a ratio of 36 beads to 9 beads

Janine needs 9 red beads and 36 blue beads to achieve a total of 45 beads in a ratio of 1:4. By dividing the total beads into 5 parts, we find the quantity of each color. Thus, the calculation gives her the correct amounts for her necklace.
