Answer 1

Answer:

Q.1) $\frac{16}{7}$

Q.2) $\frac{7}{60}$

Q.3) $- \frac{3}{10}$

Q.4) $- \frac{5}{6}$

Step-by-step explanation:

Q.1) $3 - \frac{5}{7} = \frac{21 - 5}{7} = \frac{16}{7}$

Q.2) $1 - \frac{4}{5} + \frac{7}{15} - \frac{11}{20} = \frac{1}{5} + \frac{1}{5}( \frac{28 - 33}{12}) \: = \frac{1}{5} - \frac{1}{12} = \frac{7}{60}$

Q.3) $- \frac{9}{16} \times \frac{8}{15} = - \frac{3}{10}$

Q.4) $- \frac{5}{9} \times \frac{3}{2} = - \frac{5}{6}$
