$\frac{3}{14}$

Step-by-step explanation:

so

$\frac{5}{14} + x = \frac{2}{21} \\ \frac{5}{14 } - \frac{2}{21} = x \\ \frac{15}{42} - \frac{4}{42} = x \\ \frac{9}{42} = x \\ \frac{3}{14} = x$

Answer 2

Answer:

Step-by-step explanation:

→ Let that number be x

→ -5/14 + x = -2/21

→x = -2/21 + 5/14

→ x = -2*2/21*2 + 5*3/14*3

→ x = -4/42 + 15/42

→ x = 11/42

→ so 11/42 should be added to - 5 upon 14 to get - 2 upon 21​.
