 1.  
Choose the decimal value that the model represents.

a.
0.24
b.
0.28
c.
0.34
d.
0.26


Solution:

The above figure represents a hundredths model formed by drawing ten equally spaced vertical lines, each divided by ten equally spaced horizontal lines.

Twenty-four out of hundred square pieces of the model are shaded.

The model represents twenty-four hundredths, or 0.24.


Correct answer : (1)
 2.  
The shaded region on the grid represents forty hundredths. How is this decimal written as a numeral?


a.
0.48
b.
0.42
c.
0.46
d.
0.40


Solution:

Forty hundredths means 40 / 100.

The decimal represented by the model = 40 / 100 = 0.40.


Correct answer : (4)
 3.  
Choose the decimal for the number that represents the shaded portion in the model.

a.
0.36
b.
0.32
c.
0.38
d.
0.30


Solution:

The above figure represents a hundredths model formed by drawing ten equally spaced vertical lines, each divided by ten equally spaced horizontal lines.

The fraction of the number of the squares shaded = 36 hundredths = 36 / 100.
[The number of squares shaded = 36.]

The decimal that represents the number of squares shaded = 0.36.


Correct answer : (1)
 4.  
What decimal does this model represent?

a.
1.5
b.
15
c.
0.15
d.
5.1


Solution:

There are two grids, each grid is divided into ten equal parts.

The first grid is 10 tenths and is hence 1 whole and the second grid five tenths. 15 / 10 describes the grid correctly.

The word name to represent the number shown by the grid is one and five tenths or can be written as 1.5 in decimal form.
[10 tenths = 1 whole which represents the first grid as the whole grid is colored.]


Correct answer : (1)
 5.  
Which of the models represents 0.9?


a.
Model 4
b.
Model 2
c.
Model 3
d.
Model 1


Solution:

Each strip in the tenths model represents one tenth of the model = 0.1.

So, 0.9 in the tenths model should have 9 colored strips out of ten equally spaced strips.
[Since 0.9 = 0.1 × 9.]

Among the choices, Model 4 represents the decimal 0.9.
[Model 4 contains 9 equal strips (tenths).]


Correct answer : (1)
 6.  
Identify the decimal that the shaded area shows.

a.
0.5
b.
5.0
c.
0.6
d.
0.4


Solution:

The given figure resembles a tenths grid where the numbers from 1 to 10 are represented from left to right.

Out of 10 grids, 5 are shaded. Therefore the decimal that the shaded area shows is 0.5.


Correct answer : (1)
 7.  
Identify the word name for the decimal that the shaded area represents.


a.
ten tenths
b.
seven tens
c.
three tenths
d.
seven tenths


Solution:

The decimal represented by the shaded area is 0.7.
[Seven out of ten equal parts are shaded in the tenths grid shown.]

So the word name for the decimal shown is seven tenths.


Correct answer : (4)
 8.  
Which of the figures represents 0.4?


a.
Figure 4
b.
Figure 2
c.
Figure 1
d.
Figure 3


Solution:

The given figure resembles a tenths grid, where the numbers from 1 to 10 are represented from left to right.

The shaded area in the tenths grid represents the decimal.

Therefore the decimal 0.4 is represented by Figure 3.


Correct answer : (4)
 9.  
Which of the following is the word name for the decimal represented by the shaded area?


a.
four tenths
b.
three tens
c.
seven tenths
d.
three tenths


Solution:

The decimal represented by the shaded area is 0.3.
[Three out of ten equal parts are shaded in the tenths grid shown.]

So, the word name for the decimal shown is three tenths.


Correct answer : (4)
 10.  
Choose the word name for the decimal represented by the shaded area.


a.
one and five tenths
b.
nine tenths
c.
five tenths
d.
eight tenths


Solution:

The decimal represented by the shaded area is 1.5.
[There are two tenths grids shown with the first one being completely shaded and in the second one, five out of ten equal parts are shaded.]

So, the word name for the decimal shown is one and five tenths.
