Question

1. write a fraction to represent the shaded area. if the fraction is improper, write the shaded area as a mixed number. do not simplify your answers.

Explanation:

Step1: Analyze the first figure

The first figure is composed of 2 congruent parallelograms, and each parallelogram is divided into 2 equal - sized triangles. The total number of equal - sized triangles is 4, and the number of shaded triangles is 2. So the fraction representing the shaded area is $\frac{2}{4}$.

Step2: Analyze the second figure

The second figure is composed of 4 congruent parallelograms, and each parallelogram is divided into 2 equal - sized triangles. The total number of equal - sized triangles is 8, and the number of shaded triangles is 4. So the fraction representing the shaded area is $\frac{4}{8}$.

Answer:

The fraction for the first figure is $\frac{2}{4}$, and the fraction for the second figure is $\frac{4}{8}$.
