Hey Mate!!

Let the number be x.

$= > \frac{3}{7} - x = \frac{11}{21} \\ = > - x = \frac{11}{21} - \frac{3}{7} \\ = > - x = \frac{11 - 9}{21} \\ = > - x = \frac{2}{21} \\ = > x = - \frac{2}{21}$

Answer 2

Step-by-step explanation:

..3/7-x = 11/21

..-x = 11/21 - 3/7

-x = 11-9

21

-x = 2/21

x = -2/21

so, 2/21 will subtract from 3 /7 to get 11/21
