Answer:
1.3
Step-by-step explanation:
We assume that each square in the model represents 1 unit. Each square is divided into 10 parts, so each of those strips represents 1/10 unit, or 0.1 when written in decimal.
There are 3 of the 0.1-unit strips colored in the second square, representing 0.3 units. The number represented by the shaded portion of the model is ...
1 + 0.3 = 1.3
