Answer 1

Answer:

-223/630

Step-by-step explanation:

$( - 2) \div 9 + 3 \div 10 + ( - 1) \div 15 + ( - 8) \div 21 \\ \frac{( - 2)}{9} + \frac{3}{10} + \frac{( - 1)}{15} + \frac{( - 8)}{21}$

LCM of 9,10,5,21 is 630

$\frac{( - 140 + 189 - 42 - 240)}{630} = \frac{ - 223}{630}$

Answer is -223/630
