Question

if a+b /a-b =4/3 then a/b =?​

Answer 1

Solution -

It is given in the question that

• $\sf{\dfrac{a + b}{a - b} = \dfrac{4}{3}}$

⠀

Cross Multiplying

$\tt\dashrightarrow{3(a + b) = 4(a - b)}$

⠀

$\tt\dashrightarrow{3a + 3b = 4a - 4b}$

⠀

Summarizing the equation

$\tt\dashrightarrow{4a - 3a = 3b + 4b}$

⠀

$\tt\dashrightarrow{a = 7b}$

⠀

Transfering b to the L.H.S

$\tt\dashrightarrow{\dfrac{a}{b} = 7}$

⠀

Hence,

• $\bf{Value\: of\: \dfrac{a}{b} \: is\: 7.}$
