Answer 1

Answer:

Solution :-

1) $\dfrac{4}{13} + \dfrac{- 5}{8} + \dfrac{- 8}{13} + \dfrac{9}{13}$

$\implies\dfrac{32 - 65 - 64 + 72}{104}$

$\implies\dfrac{- 33 + 8}{104}$

$\implies\dfrac{- 25}{104}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\:\dfrac{- 25}{104}$

2) $\dfrac{3}{8} + \dfrac{7}{2} + \dfrac{- 3}{5} + \dfrac{9}{8} + \dfrac{- 3}{2} + \dfrac{6}{5}$

$\implies\dfrac{3}{8} + \dfrac{9}{8} + \dfrac{7}{2} + \dfrac{- 3}{2} + \dfrac{- 3}{5} + \dfrac{6}{5}$

$\implies\dfrac{3 + 9}{8} + \dfrac{7 - 3}{2} + \dfrac{- 3 + 6}{5}$

$\implies\dfrac{12}{8} + \dfrac{4}{2} + \dfrac{3}{5}$

$\implies\dfrac{60 + 80 + 24}{40}$

$\implies\cancel{\dfrac{164}{40}}$

$\implies\dfrac{41}{10}$

$\implies 4.1$

$\therefore$ $\sf\: The\: answer\: of \:this\: question\: is\: 4.1$

3) $\dfrac{5}{8} + \dfrac{3}{- 2} + \dfrac{- 7}{3} + 3$

$\implies\dfrac{15 - 36 - 56 + 72}{24}$

$\implies\dfrac{- 21 + 16}{24}$

$\implies\dfrac{- 5}{24}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: \dfrac{- 5}{24}$

4) $\dfrac{1}{8} + \dfrac{5}{12} + \dfrac{2}{7} + \dfrac{7}{12} + \dfrac{9}{7} + \dfrac{- 5}{16}$

$\implies\dfrac{1}{8} + \dfrac{- 5}{16} + \dfrac{5}{12} + \dfrac{7}{12} + \dfrac{2}{7} + \dfrac{9}{7}$

$\implies\dfrac{2 - 5}{16} + \dfrac{5 + 7}{12} + \dfrac{2 + 9}{7}$

$\implies\dfrac{- 3}{16} + \dfrac{12}{12} + \dfrac{11}{7}$

$\implies\dfrac{- 63 + 336 + 528}{336}$

$\implies\cancel{\dfrac{801}{336}}$

$\implies\dfrac{267}{112}$

$\implies 2.383$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: 2.383$

5) $\dfrac{- 3}{10} + \dfrac{7}{15} + \dfrac{3}{- 20} + \dfrac{- 9}{10} + \dfrac{13}{15} + \dfrac{13}{- 20}$

$\implies\bigg(\dfrac{- 3}{10} + \dfrac{- 9}{10}\bigg) + \bigg(\dfrac{7}{15} + \dfrac{13}{15}\bigg) + \bigg(\dfrac{3}{- 20} + \dfrac{13}{- 20}\bigg)$

$\implies\bigg(\dfrac{- 3 - 9}{10}\bigg) + \bigg(\dfrac{7 + 13}{15}\bigg) + \bigg(\dfrac{- 3 - 13}{20}\bigg)$

$\implies\dfrac{- 12}{10} + \dfrac{20}{15} + \dfrac{- 16}{20}$

$\implies\dfrac{- 72 + 80 - 48}{60}$

$\implies\cancel{\dfrac{- 40}{60}}$

$\implies\dfrac{- 2}{3}$

$\therefore\sf\: The\: answer\: of\: this\: question\: is\: \dfrac{- 2}{3}$
