Question

if a/b=-2/3and c/d=+5/18then show that (a/b+c/d) =(c/d+a/b)​

Answer 1

Step-by-step explanation:

The value of a/b + c/d = -2/3 + 5/18

[-2(6)+5]/18

= (-12+5)/18

= -7/18

The value of c/d + a/b = 5/18 + (-2)/3

= [5+(-2)(6)]/18

= (5-12)/18

= -7/18

LHS=RHS

Hence proved.

Answer 2

Answer:

(a/b + c/d) = (c/d + a/b) = -7/18

Explanation below

Step-by-step explanation:

a/b=-2/3 , c/d=5/18

Equation 1 :

(a/b + c/d) = -2/3 + 5/18

= LCM of 3 and 18 is 18

Therefore, -2/3 + 5/18 = (-12+5)/18

= (a/b + c/d) = -7/18

Equation 2 :

(c/d + a/b) = 5/18 + (-2/3)

= LCM of 3 and 18 is 18

Therefore, 5/18 + (-2/3) = (5-12)/18

= (c/d+ + a/b) = -7/18

Comparing Equation 1 and Equation 2,

-7/18 = -7/18

So, We can conclude that (a/b + c/d) = (c/d + a/b)
