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.
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 up together?
3. Sohan was putting covers on his note books.
He put one fourth of the covers on Monday.

Or Shekhar ate 2 chapatis
for lunch and 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.
