The ratio of blue triangles to all triangles is:
Blue triangles: 5
All triangles: 5 + 80 = 85
Then, the ratio is as follows:
[tex]\frac{5}{85}=\frac{1}{17}[/tex]We divided the numerator and the denominator by 5, and we ended up with 1/17.
Therefore, in simplified form, the ratio of blue triangles to all triangles is 1/17.
