Respuesta :

If there are 45 beads, with a ratio of [tex]1:4[/tex]
Then,
[tex]\frac{45}{5}=9[/tex]
Then if [tex]\frac{1}{4}=\frac{9}{x}[/tex]
Then [tex]x=9*4[/tex]
Therefore, [tex]x=36[/tex]
Meaning, there would be a ratio of 36 beads to 9 beads

Answer:

9 red and 36 blue

Step-by-step explanation:

1+4=5 so 45/5=9
