Question

By suitable arrangement find the sum of the following: -9/5+(2/-3)+1/5+3/5​

Answer 1

Answer:

$-\frac{5}{3}$

Step-by-step explanation:

$-\frac{9}{5}+\left(\frac{2}{-3}\right)+\frac{1}{5}+\frac{3}{5}$

$-\frac{9}{5}+\frac{1}{5}+\frac{3}{5}+\left(\frac{2}{-3}\right)$

$=\frac{-9+1+3}{5}$

$-1+\left(\frac{2}{-3}\right)$

$-1-\frac{2}{3}$

$-\frac{1\cdot \:3}{3}-\frac{2}{3}$

$=\frac{-1\cdot \:3-2}{3}$

$\frac{-5}{3}$

= $-\frac{5}{3}$
