FRACTIONS:
Fractions represent
equal parts of a whole or a collection.
Fraction of a whole:
When we divide a whole into equal parts, each part is a fraction.
Fraction notation: (p/q)
A fraction has two parts:
Numerator and Denominator.
The number on the top of
the line is called the numerator. It tells how many equal parts of the whole or
collection are taken.
The number below the line is called the
denominator. It shows the total divisible number of equal parts the whole
into or the total number of equal parts which are there in a collection.
Examples:
Figure(i):
It
represents the whole part.
Figure(ii):
The number of parts are 2. The
shaded part is 1.The Fraction of
parts shaded = 1/2.
Figure(iii):
The
number of parts are 3.The shaded
parts are 2. The Fraction of parts shaded = 2/3.
Figure(iv):
The
numbers of parts are 4.The shaded
parts are 3. The Fraction of parts Shaded = 3/4.
Figure(v):
The number of diamonds = 6. The number of diamonds coloured= 3. The Fraction of diamonds coloured = 3/6.
Figure(vi):
The
number of stars = 7. The number of
stars coloured = 5. The Fraction of
stars coloured = 5/7.
Therefore,
Fraction
= Number of parts coloured or shaded / Total number of parts.
