Answer 1

Answer:

Step-by-step explanation:

1/4×2/7-(-5/21)+(-3/7)×9/2

2/14 + 5/21 - 3/7 × 9/2

2/14 + 5/21 - 27/14

6+10/42 - 27/14

16/42 - 27/14

16-81/42

-65/42

Answer 2

$\frac{1}{4}*\frac{2}{7}-\frac{(-5)}{21} +\frac{(-3)}{7} *\frac{9}{2}$

BODMAS - Multiplication

$\frac{1}{14} - \frac{(-5)}{21} +\frac{-27}{14}$

BODMAS- Addition

$\frac{(-13)}{7} - \frac{(-5)}{21}$

$\frac{(-39)}{21}-\frac{(-5)}{21}$

$\frac{(-34)}{21}$

∴The answer is $\frac{(-34)}{(21}$
