Answer 2

Step-by-step explanation:

Solution:

Given expression,

3/7+(-6/11)+(-8/21)+(5/22)

→ [(3/7) + (-8/21)] + [(-6/11) + (5/22)]

(क्रमविनिमेयता और साहचर्यता के उपयोग से)

→ [{(3*3) + (-8) * 1}/21] + [{(-6) * 2 + 5 * 1}/22]

→ [{9 + (-8)}/21] + [(-12 + 5)/22]

→ (1/21) + (-7/22)

→ {1 * 22 * + (-7) * 21}/462

→ (22 - 147)/462

→ -125/462 Ans.
