2. If the whole bar is 3 units long, what is the length of the shaded part of the bar? Write a multiplication
equation for the diagram, and then solve.

see the explanation

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The fraction of the shaded part is equal to divide the number of shaded parts divided by the total number of parts

so

Let

x ----> the number of shaded parts

y ----> the total number of parts

we have

x=3, y=4

so

To find out the length of the shaded part, multiply the fraction of the shaded parts by the total length of the bar
