Question

If a= 2/5 and b = 1/3then find a+b divide by a-b

Answer 1

Step-by-step explanation:

Given:-

a=2/5

b=1/3

To find:-

$\\ \tt{:}\rightarrowtail \dfrac{a+b}{a-b}$

Solution:-

$\\ \tt{:}\rightarrowtail a+b=\dfrac{2}{5}+\dfrac{1}{3}$

$\\ \tt{:}\rightarrowtail a+b=\dfrac{6+5}{15}$

$\\ \bf{:}\rightarrowtail a+b=\dfrac{11}{15}$

and

$\\ \tt{:}\rightarrowtail a-b=\dfrac{2}{5}-\dfrac{1}{3}$

$\\ \tt{:}\rightarrowtail a-b=\dfrac{6-5}{15}$

$\\ \tt{:}\rightarrowtail a-b=\dfrac{1}{15}$

Now

$\\ \tt{:}\rightarrowtail \dfrac{a+b}{a-b}=\dfrac{\frac{11}{15}}{\frac{1}{15}}$

$\\ \tt{:}\rightarrowtail \dfrac{11}{1}$

$\\ \tt{:}\rightarrowtail 11$
