Answer:
Number of red beads = 6
Number of blue beads = 15
Step-by-step explanation:
Number of total beads = 21
Ratio of red beads to the blue beads = 2 : 5
Therefore, number of red beads I have = [tex]\frac{2}{2+5}(\text{Total number of beads})[/tex]
= [tex]\frac{2}{7}\times 21[/tex]
= 6 beads
Number of blue beads = [tex]\frac{5}{2+5}\times (21)[/tex]
= [tex]\frac{5}{7}\times 21[/tex]
= 15 beads
Therefore, number of red beads = 6
And number of blue beads = 15
