1 Whole

1  =

=

=

Or,

1 whole  =  x tenths
1 whole  =  100 hundredths
1 whole  =  thousand thousandths

one tenth  =  0.one
1 hundredth  =  0.01
ane thousandth  =  0.001

Understanding Tenths

0.5, 0.7 and 0.two are decimals or decimal numbers.

Divide 1 whole into 10 equal parts.

In the fraction class, each part has a value equal to

or i tenth.

In the decimal form, each part has a value equal to 0.1 (read as zero point 1).

Two parts are

or 2 tenths or 0.2.

The dot in a decimal number is called a decimal point.

1. What decimals do the following shaded parts represent?

a)

4 tenths

= 0.4

b)

3 tenths

=  0.iii

c)

10 tenths
x tenths  =  1 whole
=  1

x tenths make 1 whole.

d)

=   2  +

=  2  +  0.3
=  2.iii

e)

two fifths

=

=    0.4

2 fifths  =  4 tenths

3. What is the value of each digit in 736.5?

In 736.v,

• the digit vii is in the hundreds place, its value is 7 × 100 or 700
• the digit 3 is in the tens place, its value is 3 × 10 or 30
• the digit half dozen is in the ones identify, its value is 6 × 1 or 6
• the digit v is in the tenths place, its value is 5 × 0.one or 0.5

700 + 30 + 6 + 0.5 = 7 iii 6 .5

Understanding Hundredths

Divide 1 whole into 100 equal parts.

In the fraction form, each part has a value equal to

or 1 hundredth.

In the decimal class, each office has a value equal to 0.01 (read as nix betoken zero one).

4. What decimals practise the following shaded parts represent?

a)

4 hundredths

=   0.04

b)

ten hundredths
x hundredths  =  1 10th
=  0.1

10 hundredths brand 1 tenth.

c)

50 hundredths

=   0.fifty

Or,

=

=    0.5

The decimals 0.5 and 0.50 have the same value.

d)

=   i  +

=  i  +  0.23
=  1.23

e)

=   iii  +

=   three  + 
=   iii  +  0.48
=   three.48

Change the denominator to a multiple of 10.

25  × four = 100

C  =  3.03

viii. Do the following.

a)   Alter $10 and 35 ¢ to dollars.

$10   and   35 ¢  =  $10  +  $0.35
=  $10.35

100 ¢  =  $1
1 ¢  =  of $ane
=  $0.01

b)   Write 4 m 65 cm in m.

4 m   65 cm  =  4 m  +  65 cm
=  4.65 m

100 cm  =  1 g
1 cm  =  thou
=  0.01 chiliad

c)   Express litres in decimal.

L   =   9 L  +

L
=   9 50   +   0.03 Fifty
=   9.03 L

Agreement Thousandths

Divide 1 whole into 1000 equal parts.

In the fraction form, each part has a value equal to

or 1 thousandth.

In the decimal form, each part has a value equal to 0.001 (read as zero point zero naught i).

ix. What decimals exercise the following fractions or mixed numbers stand for?

a)   eight thousandths
8 thousandths  =

= 0.008

b)  

=

+

=  2  +  0.607
= 2.607

c)  

=   5  +

=   5  +  0.300
= 5.300

Or,

=   v  +

=   v  + 
=   5  +  0.3
= five.3

The decimals 5.300 and 5.iii have the same value.
