Question

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.

Answer 1

Answer:

The length of the shaded part is $\frac{9}{4}$

Step-by-step explanation:

The original figure, which you may have unintentionally missed to add, is attached below.

From the figure, it is easy to figure out that:

• The whole bar is 3 units long.

• The bar has 4 total parts.

• The shaded region has 3 parts.

So, the ratio of shaded parts to total parts will be: $\frac{3}{4}$

In order to determine length of the shaded part, just multiply the ratio of the shaded parts to total parts by the total length of the bar.

So,

         $\frac{3}{4} \times3=\frac{9}{4}$

Therefore, the length of the shaded part is $\frac{9}{4}$

Answer 2

Answer:

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

$\frac{3}{4}$

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

so

$\frac{3}{4}(3)=\frac{9}{4}=2.25\ units$
