**Addition and Subtraction of Fractions**

So far in our study we have learnt about natural numbers, whole numbers and

then integers. In the present chapter, we are learning about fractions, a different

type of numbers.

Whenever we come across new type of numbers, we want to know how to

operate with them. Can we combine and add them? If so, how? Can we take

away some number from another? i.e., can we subtract one from the other?

and so on. Which of the properties learnt earlier about the numbers hold now?

Which are the new properties? We also see how these help us deal with our

daily life situations.

**Try These:-**

1. My mother divided an apple into 4 equal

parts. She gave me two parts and my

brother one part. How much apple did she

give to both of us together?

2. Mother asked Neelu and her brother to

pick stones from the wheat. Neelu picked

one fourth of the total stones in it and her

brother also picked up one fourth of the

stones. What fraction of the stones did both

pick up together?

3. Sohan was putting covers on his note books.

He put one fourth of the covers on Monday.

He put another one fourth on Tuesday and

the remaining on Wednesday. What fraction

of the covers did he put on Wednesday?

Look at the following

example. A tea stall owner

consumes in her shop 2 1

2

litres of milk in the morning

and 1

1

2 litres of milk in the

evening. What is the total

amount of milk she uses in

the stall?

Or Shekhar ate 2 chapatis

for lunch and 1

1

2 chapatis for

dinner. What is the total

number of chapatis he ate?

Clearly, both the situations

require the fractions to be added. Some of these additions can be done orally

and the sum can be found quite easily.

Adding or subtracting like fractions

All fractions cannot be added orally. We need to know how they can be added

in different situations and learn the procedure for it. We begin by looking at

addition of like fractions.

Take a 7 Ć 4 grid sheet (Fig 7.13). The sheet has

seven boxes in each row and four boxes in each

column.

How many boxes are there in total?

Colour five of its boxes in green.

What fraction of the whole is the green region?

Now colour another four of its boxes in yellow.

What fraction of the whole is this yellow region?

What fraction of the whole is coloured altogether?
