Математика 5 класс помогите срочно!​

Answer 1

Ответ:

$\frac{3}{4} = \frac{25*3}{25*4} =\frac{75}{100} \\\frac{1}{2} = \frac{50*1}{50*2} = \frac{50}{100} \\\frac{3}{5} = \frac{20*3}{20*5} = \frac{60}{100} \\\frac{3}{10} = \frac{10*3}{10*10} = \frac{30}{100} \\\frac{9}{20} = \frac{5*9}{5*20} = \frac{45}{100} \\\frac{2}{25} = \frac{4*2}{4*25} = \frac{8}{100} \\\frac{9}{50} = \frac{2*9}{2*50} = \frac{18}{100}$
