ГДЗ по математике 5 класс Мерзляк ФГОС Задание 887

\[\boxed{\mathbf{887}\mathbf{\ (752)}.\ Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ \frac{x}{72} - \frac{13}{72} = \frac{29}{72}\]

\[x - 13 = 29\]

\[x = 29 + 13\]

\[x = 42\]

\[Ответ:42.\]

\[2)\ \frac{29}{43} - \left( m + \frac{13}{43} \right) = \frac{5}{43}\]

\[m + \frac{13}{43} = \frac{29}{43} - \frac{5}{43}\]

\[m = \frac{24}{43} - \frac{13}{43}\]

\[m = \frac{11}{43}\]

\[Ответ:\frac{11}{43}.\]
