Question

Camille shaded 18/30 of a model. Write the decimal that represents the unshaded portion of the model

Answer 1

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

$30-18=12$

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

$\frac{12}{30}=0.4$
