Ihave 3 types of shapes: triangle, square or circle in the ratio 3: 6: 1. the triangles are either red or blue. the ratio of red triangles to blue triangles is 4: 5. given that i have 12 red triangles, how many circles are there

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 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 = circles

Therefore, you will have 9 circles.
