Answer: 37
Step-by-step explanation:
Given that:
Total number of beads on her necklace = 50
Percentage of blue beads = 26%
Therefore, number of blue beads :
Percentage number of blue beads × total number of beads on necklace
Number of Blue beads = 26% × 50
= 0.26 × 50 = 13
Number of Blue beads = 13
Therefore, number of beads that aren't blue :
Total number of beads - number of blue beads
50 - 13 = 37
Number of beads that aren't blue = 37
