Each shape is 1 whole. What fraction is represented by the shaded part of the model?

lubasha [3.4K]

Answer:

$\frac{2}{1}$

Step-by-step explanation:

Each shape is 1 whole.

In the given image, there are 4 parts in each shape.

The shaded part in the first shape is 4.

The fraction of the shaded part in the first shape

$=\frac{Number of shaded part}{Total part of the fraction}=\frac{4}{4}$

The shaded part in the second shape is 4.

The fraction of the shaded part in the second shape

$=\frac{Number of shaded part}{Total part of the fraction}=\frac{4}{4}$

The shaded part of the model $=\frac{4}{4}+\frac{4}{4}$

$=\frac{1}{1}+\frac{1}{1}$

$= \frac{2}{1}$

Hence, the fraction represented by the shaded part of the model is $\frac{2}{1}$ .
