Answer 1

Answer:

$\dfrac{-19}{17}$

Explanation:

Given values :-

x = $\dfrac{1}{10}$ , y = $\dfrac{9}{5}$

Equation formed :-

($\dfrac{1}{10}$ + $\dfrac{9}{5}$) ÷ ( $\dfrac{1}{10}$ - $\dfrac{9}{5}$)

= ( $\dfrac{1+18}{10}$) ÷ ( $\dfrac{1-18}{10}$)

= $\dfrac{19}{10}$ ÷ $\dfrac{-17}{10}$

= $\dfrac{19}{10}$ × $\dfrac{10}{-17}$

= $\dfrac{-19}{17}$
