Question

What should be added to twice -7/3 to get 3/7 ?

Answer 1

Let x be added.


2(-7/3)+x=3/7


Multiplying 2 with-7/3


-14/3+x=3/7

Taking-14/3 to the right side and when taken to right side it will become positive.


x=3/7+14/3

Taking LCM of 7 and 3 i.e. 21

x=3*3/21+14*7/21

x=9/21+98/21

Adding

x=9+98/21

x=107/21

So 107/21 should be added to the fraction for getting 3/7.
