Answer 1

Answer:

$a) \frac{5}{4} + ( - \frac{11}{4} ) \\ \\ l.c.m = 4 \\ \\ = \frac{5 - 11}{4} \\ = \frac{ - 6}{4} = - \frac{3}{2} \\ \\ \\ b) \frac{5}{3} + \frac{3}{5} \\ \\ l.c.m = 15 \\ \\ = \frac{25 + 9}{15} = \frac{34}{15} \\ \\ \\ a) \frac{9}{2} \times ( - \frac{7}{4} ) \\ \\ = - \frac{63}{8} \\ \\ b) \frac{3}{11} \times \frac{2}{5 } \\ \\ = \frac{6}{55}$
