Answer:
Q.1) [tex] \frac{16}{7} [/tex]
Q.2) [tex] \frac{7}{60} [/tex]
Q.3) [tex] – \frac{3}{10} [/tex]
Q.4) [tex] – \frac{5}{6} [/tex]
Step-by-step explanation:
Q.1) [tex]3 – \frac{5}{7} = \frac{21 – 5}{7} = \frac{16}{7} [/tex]
Q.2) [tex]1 – \frac{4}{5} + \frac{7}{15} – \frac{11}{20} = \frac{1}{5} + \frac{1}{5}( \frac{28 – 33}{12}) \: = \frac{1}{5} – \frac{1}{12} = \frac{7}{60} [/tex]
Q.3) [tex] – \frac{9}{16} \times \frac{8}{15} = – \frac{3}{10} [/tex]
Q.4) [tex] – \frac{5}{9} \times \frac{3}{2} = – \frac{5}{6} [/tex]
