Answer:
You will have 9 circles.
Step-by-step explanation:
The ratio of red triangles to blue triangles is 4:5
This means that for every 4 red triangles, you have 5 blue triangles.
And given is that you have 12 red triangles , so you would have 15 blue triangles.
Now in total you have [tex]12+15=27[/tex] triangles.
The ratio of triangles to circles is 3:1
This means for every 3 triangles, you have 1 circle.
As you have 27 triangles, we can say that there are three times as many triangles as circles.
Hence, circle will be = [tex]27/3=9[/tex] circles
Therefore, you will have 9 circles.
