Answer 1

Answer:

11 - (-11/7 -5/21

Step-by-step explanation:

11 - (-11/7 -5/21)

Answer 2

➤ Answer :-

$\dashrightarrow \sf( - 11) - \bigg( \frac{( - 11)}{7} - \frac{( - 5)}{21} \bigg )$

$\dashrightarrow \sf \frac{( - 11)}{1} - \frac{( - 11)}{7} - \frac{( - 5)}{21}$

LCM of 1,7 and 21 is 21.

$\dashrightarrow \sf \frac{( - 11) \times 21}{1 \times 21} - \frac{( - 11) \times 3}{7 \times 3} - \frac{( - 5)}{21}$

$\dashrightarrow \sf \frac{( - 231)}{21} - \frac{( - 33)}{21} - \frac{( - 5)}{21}$

$\dashrightarrow \sf \frac{( - 231) - ( - 33) - ( - 5)}{21}$

$\dashrightarrow \sf \frac{( - 231) -( 33) - (5)}{21}$

$\dashrightarrow \sf \frac{( - 269)}{21}$

$\Huge\therefore$The answer is $\sf\frac{(-269)}{21}$
