Answer 1

Given :

• (a + b)/(a - b) = 4/3

To Find :

• Find the value of ab ?

Solution :

According to the question :

➣ (a + b)/(a - b) = 4/3

• Cross multiplication

➣ 3(a + b) = 4(a - b)

➣ 3a + 3b = 4a - 4b

➣ 3b + 4b = 4a - 3a

➣ 7b = a

➣ 7 = a/b

➣ a/b = 7

Hence,

• The value of a/b is 7.
