Answer 1

Question:

(a + b)/(a - b) where a = 1/2 and b = 2/3

Answer:

-7

$\rule{200}2$

Step-by-step explanation:

Given that a is 1/2 and b is 2/3. What we have to do is simply substitute the value of a and b in (a + b)/(a - b) to find it's value.

→ (1/2 + 2/3)/(1/2 - 2/3)

LCM of 2 and 3 is 6

→ [(3 + 4)/6]/[(3 - 4)/6]

→ (7/6)/(-1/6)

→ 7/6 × 6/(-1)

→ 7/(-1)

On solving we get,

→ -7

Hence, the value of (a + b)/(a - b) is -7 when a is 1/2 and b is 2/3.
