Question

find ( a+b)/(a-b) if a=1/2 b=2/3 this is the question friends​

Answer 1

Answer:

Ans:-5

Step-by-step explanation:

$\frac{a + b}{a - b}$

$= \frac{ \frac{1}{2} + \frac{2}{3} }{ \frac{1}{2} - \frac{2}{3} }$

$= \frac{ \frac{3 + 2}{6} }{ \frac{3 - 2}{6} }$

$= \frac{ \frac{5}{6} }{ \frac{1}{6} }$

$= \frac{5}{6} \times 6$

$= 5$

Answer 2

Step-by-step explanation:

Value of a= 1/2, b= 2/3

(a+b) / ( a-b)

Solve-

(1/2+2/3) / (1/2-2/3)

There LCM is ,6

(3/6+4/6) / (3/6 - 4/6)

(7/6) / ( 1/6)

(7× -6)/6

-42/6

= -7
