Answer:
The decimal that represents the unshaded portion of the model is 0.4
Step-by-step explanation:
we know that
Camille shaded 18/30 of a model
That means
The total parts of the model is equal to 30
The shaded parts of the model is 18
To find out the unshaded parts of the model subtract the shaded parts from the total parts
[tex]30-18=12[/tex]
To find out the decimal that represents the unshaded portion of the model, divide the unshaded parts of the model by the total parts of the model
so
[tex]\frac{12}{30}=0.4[/tex]
