Write the following as numbers in the given table.

One block divided into 10 equal parts means each part is 1/10 (one-tenth) of a unit. It can be written as 0.1 in decimal notation. One block divided into 100 equal parts means each part is (1/100) one-hundredth of a unit.

Write the following decimals in the place value table.

(a) 19.4

(b) 0.3

(c) 10.6

(d) 205.9

Write each of the following as decimals:

(a) Seven-tenths

(b) Two tens and nine-tenths

(c) Fourteen-point six

(d) One hundred and two ones

(e) Six-hundred-point eight

(a)Seven-tenths

=7/10 =.7

(b) Two tens and nine tenths = 20 + 9/10 =20 +.9=20.9

(c)Fourteen point six = 14.6

(d) One hundred and two ones = 100 + 2 = 102

(e) Six hundred point eight = 600.8

Write each of the following as decimals:

(a) $\frac {5}{10}$

(b) $3 + \frac {7}{10}$

(c) $200 + 60 +5 + \frac {1}{10}$

Express the following as cm using decimals.

(a) 2 mm

(b) 30 mm

(c) 116 mm

(d) 4 cm 2 mm

(e) 162 mm

(f) 83 mm

We know that 10 mm =1 cm i.e. 1 mm is 1/10 of centimeter

(a)2 mm = 2/10 cm = .2 cm

(b) 30mm = 30/10 cm = 3 cm

(c) 116 mm= 116/10 cm = 11.6 cm

(d) 4 cm 2 mm= (4 + 2/10) cm = 4.2 cm

(e) 162 mm = 162/10 cm = 16.2 cm

(f) 83 mm = 83/10 cm = 8.3 cm

Between which two whole numbers on the number line are the given numbers lie? Which of these whole numbers is nearer the number?

(a) 0.8

(b) 5.1

(c) 2.6

(d) 6.4

(e) 9.1

(f) 4.9

(a) 0.8 = 0 + 8/10

So, it lies between 0 and 1 and is nearer to 1.

(b)5.1 = 5 + 1/10

So, it lies between 5 and 6 and is nearer to 5.

(c)2.6 = 2 + 6/10

So, it lies between 2 and 3 and is nearer to 3.

(d) 6.4 = 6 + 4/10

So, it lies between 6 and 7 and is nearer to 6.

(e) 9.1 = 9 + 1/10

So, it lies between 9 and 10 and is nearer to 9.

(f) 4.9 = 4 + 9/10

So, it lies between 4 and 5 and is nearer to 5.

Show the following numbers on the number line.

(a) 0.2

(b) 1.9

(c) 1.1

(d) 2.5

a) 0.2 lies between 0 and 1. There are 2 tenths in it. Divide the unit length into 10 equal parts and 0.2 represents the 2

b) 1.9 lies between 1 and 2. There are 9 tenths in it. 1.9 represents the ninth part after 1.

c) 1.1 lies between 1 and 2. There are 1 tenth in it. 1.1 represents the first part after 1.

d) 2.5 lies between 2 and 3. There are 5 tenths in it. 2.5 represents the fifth part after 2.

Write the decimal number represented by the points A, B, C, D on the given number line?

a) |
A |
A represents the 8 ^{th} equal part between 0 and 1. So, A is 0.8. |

b) |
B |
B represents the 3 ^{rd} equal part between 1 and 2. So, B is 1.3 |

c) |
C |
C represents the 2 ^{nd} equal part between 2 and 3 and hence is the number 2.2 |

d) |
D |
D is 2.9, the 9 ^{th} equal part between 2 and 3. |

(a) The length of Ramesh’s notebook is 9 cm 5 mm. What will be its length in cm?

(b) The length of a young gram plant is 65 mm. Express its length in cm.

We know that 10 mm =1 cm i.e. 1 mm is 1/10 of centimeter

a) length= 9cm5mm = 9 + 5/10= 9.5 cm

b) length= 65mm =65/10= 6.5 cm

Complete the table with the help of these boxes and use decimals to write the number.
