Answer 1

1)

$( \frac{3}{4} + \frac{1}{20} ) \times \frac{1}{2} = \frac{4}{5} \times \frac{1}{2} = \frac{2}{5}$

2)

$( \frac{7}{12} - \frac{1}{3}) \times \frac{16}{19} = \frac{1}{4} \times \frac{16}{19} = \frac{4}{19}$

3)

$(7 \frac{3}{5} - 2 \frac{4}{15} ) \times \frac{9}{32} = 5 \frac{1}{3} \times \frac{9}{32} = 1 \frac{1}{2}$

4)

$( \frac{11}{24} + \frac{1}{6}) \times 1 \frac{3}{5} = \frac{7}{24} \times 1 \frac{3}{5} = \frac{7}{15}$

5)

$(5 \frac{1}{2} + 2 \frac{3}{5} ) \times \frac{5}{9} = 8 \frac{1}{10} \times \frac{5}{9} = 4 \frac{1}{2}$

6)

$(7 - 2 \frac{5}{16} ) \times \frac{4}{25} = 4 \frac{11}{16} \times \frac{4}{25} = \frac{3}{4}$
