Question

3/7+{-6/11}+{-8/21}+
{5/22}
​

Answer 1

Answer:

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

= 3/7 - 6/11 - 8/21 + 5/22

= now we need to take l. c. m for 7,11,21,22

so the l.. c. m = 462

198 - 252- 176 + 105/462

= 303 - 428 / 462

= - 125/462

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.
