​

Answer 1

a)

$\frac{1}{2} + ( - \frac{3}{5} ) \\ \\ - \frac{1}{2} \times \frac{5}{3} \\ \\ - \frac{5}{6}$

b)

$- \frac{1}{2} + ( - \frac{4}{7} ) \\ \\ \frac{1}{2} \times \frac{7}{4} \\ \\ \frac{7}{8}$

c)

$\frac{7}{5} \div \frac{3}{8} \\ \\ \frac{7}{5} \times \frac{8}{3} \\ \\ \frac{56}{15}$

d)

$\frac{ 3 }{5} \div ( - \frac{1}{3} ) \\ \\ - \frac{3}{5} \times 3 \\ \\ - \frac{9}{5}$

e)

$\frac{1}{4} \times \frac{1}{5} \div \frac{2}{7} \\ \\ \frac{1}{4} \times \frac{1}{5} \times \frac{7}{2} \\ \\ \frac{7}{40}$

f)

$( - \frac{3}{4} ) \div ( - \frac{2}{7} ) + \frac{7}{3} \\ \\ \frac{1}{4} \times ( \frac{7}{2} ) \times 7 \\ \\ \frac{49}{8}$

g)

$( - \frac{3}{4} ) \div ( - \frac{2}{7} ) \div ( - \frac{3}{5} ) \\ \\ - \frac{3}{4} \times \frac{7}{2} \times \frac{5}{3} \\ \\ - \frac{1}{4} \times \frac{7}{2} \times 5 \\ - \frac{35}{8}$
