Activity-2
Objective: To find the sum of two rational numbers with different denominator.
Eg:
Like this…We make a 7 X 3 grid because
the denominator in both the given
rational numbers are 7
and 3 resp.
This “+” sign is to represent
This “-” sign is to represent
Enclose one “+” sign with one “-” sign (Fig. 4)
Now, count the unenclosed signs in Fig 4
Only 1 is left
Result: The rational number represented by unenclosed signs
is
So,
