Answer 1

Ответ:

$\frac{7}{50} < \frac{9}{25}<\frac{2}{5}<\frac{1}{2}<\frac{13}{20}$

Пошаговое объяснение:

$\frac{2}{5}=0.4\\\frac{13}{20}=0.65\\\frac{1}{2}=0.5\\\frac{7}{50}=0.14\\\frac{9}{25}=0.36$

$0.14<0.36<0.4<0.5<0.65$

$\frac{7}{50} < \frac{9}{25}<\frac{2}{5}<\frac{1}{2}<\frac{13}{20}$

Answer 2

                   $\frac{2}{5};$   $\frac{13}{20};$  $\frac{1}{2};$  $\frac{7}{50};$  $\frac{9}{25}$

$\frac{2}{5} =\frac{2*20}{5*20}=\frac{40}{100}$

$\frac{13}{20} =\frac{13*5}{20*5}=\frac{65}{100}$

$\frac{1}{2} =\frac{1*50}{2*50}=\frac{50}{100}$

$\frac{7}{50} =\frac{7*2}{50*2}=\frac{14}{100}$

$\frac{9}{25} =\frac{9*4}{25*4}=\frac{36}{100}$

                 $\frac{14}{100}<\frac{36}{100}<\frac{40}{100}<\frac{50}{100}<\frac{65}{100}$

                  $\frac{7}{50}<\frac{9}{25}<\frac{2}{5}<\frac{1}{2}<\frac{13}{20}$

Ответ:     $\frac{7}{50};$  $\frac{9}{25};$  $\frac{2}{5};$  $\frac{1}{2};$  $\frac{13}{20}$
