Answer:
Color in 2 columns of blocks
Explanation:
The question is telling you to shade 2/5 of the shape. The given shape is divided into 4 rows and 5 columns(vertical rows). Therefore, it will be easiest to go by columns.
If the shape is divided into 5 columns and you need to shade in 2/5 of the shape, then that means you need to shade in 2 columns of the shape.
