Question

what should be added twice the rational number -7/3toget 3/7

Answer 1

first yake out their lcm and then sub 3/7 from -7/3

Answer 2

Heya !!




2 × -7/3 = -14/3



Let X should be added to -14/3 to get 3/7.




Therefore,



-14/3 + X = 3/7




-14 + 3X = 3 × 3/7




3X = 9/7 + 14




3X = 9 + 98/7




3X = 107/7



X = ( 107/7 × 3 )



X = 107/21.




Hence,


107/21 should be added to -14/3 to get 3/7.
