Ответ:

Пошаговое объяснение:

1)

a)$\frac{1}{2}$  б)$\frac{1}{8}$ в)$\frac{1}{25}$

2)

$120*\frac{1}{6} =\frac{120}{1} *\frac{1}{6} =\frac{20}{1} =20$

Ответ:20 кг

3)

$\frac{3}{8} <\frac{5}{8}$

$\frac{9}{11} >\frac{7}{11}$

$\frac{20}{21} >\frac{16}{21}$

$\frac{5}{9}< 1=\frac{5}{9} <\frac{9}{9}$

4)

$\frac{3}{8} +\frac{1}{8} =\frac{4}{8} =\frac{1}{2}$

$\frac{9}{11} +\frac{7}{11} =\frac{16}{11} =1\frac{5}{11}$

$\frac{20}{21} +\frac{16}{21} =\frac{36}{21} =1\frac{15}{21}$

$\frac{5}{9} +\frac{2}{9} =\frac{7}{9}$

$\frac{7}{10} -\frac{3}{10} =\frac{4}{10} =\frac{2}{5}$

$\frac{37}{80} -\frac{9}{80} =\frac{28}{80} =\frac{7}{20}$

$\frac{7}{25} -\frac{2}{25} =\frac{5}{25} =\frac{1}{5}$

$\frac{11}{15} -\frac{1}{15} +\frac{2}{15} =\frac{10}{15} +\frac{2}{15} =\frac{12}{15} =\frac{4}{5}$
