Question

find (a+b)÷(a-b) if
a=-3/5,b=2/15​

Answer 1

Step-by-step explanation:

We have,

a = -3/5, b = 2/15

Therefore,,

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

$\sf{=\frac{\frac{-3}{5}+\frac{2}{15}}{\frac{-3}{5}-\frac{2}{15}}}$

$\sf{=\frac{\frac{-9+2}{15}}{\frac{-9-2}{15}}}$

$\sf{=\frac{\frac{-7}{15}}{\frac{-11}{15}}}$

$\sf{=\frac{-7}{15}\times\frac{15}{-11}}$

$\sf{={\boxed{\frac{7}{11}}}}$

Hope it helps ❣️❣️❣️

Answer 2

Step-by-step explanation:

a=3/5,b=2/15

(a+b)÷(a-b)

(3/5+2/15)÷(3/5-2/15)

(3+2/75) ÷ (3-2/75)

5÷1/75

5/75=15
