Let
T-------> number of triangles in the data set
C-------> number of circles in the data set
S-------> number of squares in the data set
N------> number of total elements in the data set
we have
\(Set=(triangle, circle, square, circle, circle, square, triangle, circle)\)
we know that
\(T=2\\ C=4\\ S=2\\ N=8\)
The ratio of triangles to circles is equal to
\(r=\frac{T}{C} \\ \\ r=\frac{2}{4}\)
Divide by \(2\) boths numerator and denominator
\(r=\frac{\frac{2}{2}}{\frac{4}{2}} \\ \\ r=\frac{1}{2}\)
therefore
the answer is
the ratio of triangles to circles is equal to \(\frac{1}{2}\)
