Question

why do gorillas need big nostrils? match to the equivalent ratio at the bottom. simplify if needed. part i. use the shapes to find the following ratios. r all squares to all circles e striped squares to striped circles s striped triangles to striped squares b striped circles to all stripes f dark circles to all squares h all circles to all shapes

Explanation:

Step1: Count the number of each type of shape

Number of all circles: $4 + 3=7$. Number of all squares: $1 + 4 = 5$. Number of striped - circles: $3$. Number of striped - squares: $4$. Number of striped - triangles: $2$. Number of all stripes: $3+4 + 2=9$. Number of dark - circles: $4$. Number of all shapes: $4 + 3+2 + 1+4=14$.

Step2: Calculate the ratios

• R: All Squares to All Circles: The ratio is $\frac{5}{7}$.
• E: Striped Squares to Striped Circles: The ratio is $\frac{4}{3}$.
• S: Striped Triangles to Striped Squares: The ratio is $\frac{2}{4}=\frac{1}{2}$.
• B: Striped Circles to All Stripes: The ratio is $\frac{3}{9}=\frac{1}{3}$.
• F: Dark Circles to All Squares: The ratio is $\frac{4}{5}$.
• H: All Circles to All Shapes: The ratio is $\frac{7}{14}=\frac{1}{2}$.

Answer:

R: $\frac{5}{7}$
E: $\frac{4}{3}$
S: $\frac{1}{2}$
B: $\frac{1}{3}$
F: $\frac{4}{5}$
H: $\frac{1}{2}$
