ANSWER
45 green bands
EXPLANATION
The ratio of red hair bands to green hair bands is
5 : 9
The total ratio is:
[tex]9 + 5 = 14[/tex]
If there are a total of 70 hair bands,
Then the number of green bands
[tex] = \frac{9}{14} \times 70[/tex]
Simplify
[tex] = 9 \times 5[/tex]
Multiply
[tex] = 45[/tex]
Therefore, there are 45 green bands.
