Question

Помогите пожалуйста!!

Answer 1

Пошаговое объяснение:

$1) \frac{12}{25} -\frac{4}{25} * \frac{9}{25} \\\\ \frac{12}{25} -\frac{4}{25} =\frac{8}{25}$

$\frac{8}{25} < \frac{9}{25}$

$2) \frac{425}{900} +\frac{50}{900} *\frac{190}{900} +\frac{21}{900} \\\\\frac{425}{900} +\frac{50}{900} =\frac{475}{900}$

$3) \frac{142}{250} +\frac{87}{250} *\frac{216}{250} +\frac{63}{250}$

$\frac{142}{250} +\frac{87}{250} =\frac{229}{250}$

$\frac{216}{250} +\frac{63}{250}=\frac{279}{250}$

$\frac{229}{250} <\frac{279}{250}$

$4) \frac{57}{70} -\frac{32}{70} *\frac{62}{70} -\frac{47}{70} \\\\\frac{57}{70} -\frac{32}{70}= \frac{25}{70}$

$\frac{25}{70} >\frac{15}{70}$
