ГДЗ по математике 6 класс Мерзляк Задание 501

\[\boxed{\mathbf{501\ (501).}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

Пояснение.

Решение.

\[1)\ 24\% = \frac{24}{100} = \frac{6}{25}\]

\[48\ :\frac{6}{25} = 48 \cdot \frac{25}{6} = 8 \cdot 25 =\]

\[= 200\]

\[2)\ 75\% = \frac{75}{100} = \frac{3}{4}\]

\[3)\ 3\frac{1}{3}\% = \frac{10}{3}\% = \frac{10}{300} = \frac{1}{30}\]

\[5\ :\frac{1}{30} = 5 \cdot 30 = 150\]

\[4)\ 108\% = \frac{108}{100} = \frac{54}{50} = \frac{27}{25}\]

\[86,4\ :\frac{27}{25} = \frac{864}{10} \cdot \frac{25}{27} =\]

\[= \frac{432}{5} \cdot \frac{25}{27} = \frac{48 \cdot 5}{1 \cdot 3} = 16 \cdot 5 =\]

\[= 80\]
