Question

$by suitable arrangement find the sum of the following$
​

Answer 1

Step-by-step explanation:

$\frac{7}{3} + ( - \frac{8}{5} ) + \frac{3}{5} + ( - \frac{2}{3} ) \\ = \frac{7}{3} - \frac{8}{5} + \frac{3}{5} - \frac{2}{3 } \\ = the \: lcm \: of \: 3 \: and \: 5 \: is \: 15 \\ = \frac{35 - 24 + 9 - 10}{15} \\ = \frac{11 - 1}{15} \\ = \frac{10}{15} \\ = \frac{2}{3}$

Answer 2

Answer:

$\frac{7}{3} + ( - \frac{8}{5} ) + \frac{3}{5} + ( - \frac{2}{3} ) \\ = \frac{7}{3} - \frac{8}{5} + \frac{3}{5} - \frac{2}{3 } \\ = the \: lcm \: of \: 3 \: and \: 5 \: is \: 15 \\ = \frac{35 - 24 + 9 - 10}{15} \\ = \frac{11 - 1}{15} \\ = \frac{10}{15} \\ = \frac{2}{3}$
