Answer 1

Answer:

$(i) \frac{( - 7)}{6} + 0 + \frac{( - 3)}{8} + \frac{14}{16} + \frac{10}{12} = \frac{( - 3)}{8} \\ (ii) \frac{4}{7} + \frac{( - 5)}{9} + \frac{( - 8)}{18} + \frac{7}{15} = \frac{4}{105} \\ (iii) \frac{6}{7} + \frac{( - 5)}{9} + \frac{( - 13)}{7} + \frac{19}{21} = \frac{( - 41)}{63} \\( iv) \frac{3}{5} + \frac{7}{3} + \frac{1}{5} + \frac{( - 2)}{5} = \frac{41}{15}$

Step-by-step explanation:

$(i) \frac{( - 7)}{6} + 0 + \frac{( - 3)}{8} + \frac{14}{16} + \frac{10}{12} \\ = \frac{( - 7)}{6} - \frac{3}{8} + \frac{14}{16} + \frac{10}{12} \\ = \frac{( - 56) - 16 + 14 + 40}{48} \\ = \frac{( - 18)}{48} \\ = \frac{( - 3)}{8} \\ (ii) \frac{4}{7} + \frac{( - 5)}{9} + \frac{( - 8)}{18} + \frac{7}{15} \\ = \frac{4}{7} - \frac{ 5}{9} - \frac{ 8}{18} + \frac{7}{15} \\ = \frac{360 - 350 - 280 + 294}{630} \\ = \frac{24}{630} \\ = \frac{4}{105} \\ (iii) \frac{6}{7} + \frac{( - 5)}{9} + \frac{( - 13)}{7} + \frac{19}{21} \\ = \frac{6}{7} - \frac{ 5}{9} - \frac{13}{7} + \frac{19}{21} \\ = \frac{54 - 35 - 117 + 57}{63} \\ = \frac{( - 41)}{63} \\( iv) \frac{3}{5} + \frac{7}{3} + \frac{1}{5} + \frac{( - 2)}{5} \\ = \frac{3}{5} + \frac{7}{3} + \frac{1}{5} - \frac{2}{5} \\ = \frac{9 + 35 + 3 - 6}{15} \\ = \frac{41}{15}$
