Question

3/7+(-6/11)+(-8/21)+5/22​

Answer 1

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.

Answer 2

Answer:

$\frac{3}{7} + ( \frac{ - 6}{11} ) + ( \frac{ - 8}{21} ) + \frac{5}{22}$

$= > \frac{3}{7} - \frac{6}{77} + \frac{ - 8}{21} + \frac{5}{22}$

$= > \frac{33}{77} - \frac{42}{77} + \frac{ - 8}{21} + \frac{5}{22}$

$= > \frac{33 - 42}{77} + \frac{ - 8}{21} + \frac{5}{22}$

$= > \frac{ - 9}{77} + \frac{ - 8}{21} \frac{5}{22}$

$= > \frac{ - 9}{77} - \frac{8}{21} + \frac{5}{22}$

$= > \frac{ - 27}{231} - \frac{88}{231} + \frac{5}{22}$

$= > \frac{ - 27 - 88}{231} + \frac{5}{22}$

$= > \frac{ - 115}{231} + \frac{5}{22}$

$= > \frac{ - 230}{462} + \frac{105}{462}$

$= > \frac{ - 230 + 105}{462}$

$= > \frac{ - 125}{462}$
