**How do we add or subtract mixed fractions?**

Mixed fractions can be written either as a whole part plus a proper fraction or

entirely as an improper fraction. One way to add (or subtract) mixed fractions

is to do the operation seperately for the whole parts and the other way is to

write the mixed fractions as improper fractions and then directly add (or

subtract) them.

Adding and subtracting fractions

We have learnt to add and subtract like fractions. It is also not very difficult to

add fractions that do not have the same denominator. When we have to add or

subtract fractions we first find equivalent fractions with the same denominator

and then proceed.

Subhash had learnt about fractions in

Classes IV and V, so whenever possible

he would try to use fractions. One

occasion was when he forgot his lunch

at home. His friend Farida invited him

to share her lunch. She had five pooris

in her lunch box. So, Subhash and

Farida took two pooris each. Then

Farida made two equal halves of the

fifth poori and gave one-half to Subhash

and took the other half herself. Thus,

both Subhash and Farida had 2 full

pooris and one-half poori.

Where do you come across situations with fractions in

your life?

Subhash knew that one-half is written as

1

2 . While

eating he further divided his half poori into two equal

parts and asked Farida what fraction of the whole poori

was that piece?

Without answering, Farida also divided her portion of the

half puri into two equal parts and kept them beside Subhash’s

shares. She said that these four equal parts together make

A Fraction

Let us recapitulate the discussion.

A fraction means a part of a group or of a region.

5

12 is a fraction. We read it as “five-twelfths”.

What does “12” stand for? It is the number of equal parts

into which the whole has been divided.

What does “5” stand for? It is the number of equal parts which have been

taken out.

Here 5 is called the numerator and 12 is called the denominator.

Name the numerator of

3

7 and the denominator of

3

Play this Game

You can play this game with your friends.

Take many copies of the grid as shown here.

Consider any fraction, say

Each one of you should shade

2 of the grid.

Proper Fractions

You have now learnt how to locate fractions on a number line. Locate the fractions

8 , , , , on separate number lines.

Does any one of the fractions lie beyond 1?

All these fractions lie to the left of 1as they are less than 1.

In fact, all the fractions we have learnt so far are less than 1. These are

proper fractions. A proper fraction as Farida said (Sec. 7.1), is a number

representing part of a whole. In a proper fraction the denominator shows the

number of parts into which the whole is divided and the numerator shows the

number of parts which have been considered. Therefore, in a proper fraction the

numerator is always less than the denominator.
