Question

2. Add the following rational numbers.

(1) 6/15and-7/25​

Answer 1

Answer:

LCM is 75

30+(-21)/75

9/75

=3/25

Answer 2

6/15 + (-7/25)

= 6/15 - 7/25 [+ × - = -]

Now, find out the LCM of both the denominators, i.e. LCM = 75

= 30 - 21 / 75

= 9 / 75

Now, reduce it to simplest form....

= 9/75 = 3/25 ans.

That's it
