Answer 1

а)

$\frac{7}{8}\cdot 1000= \frac{7\cdot 125}{1}=875 \ kg$

$\frac{4}{25}\cdot 1000 = \frac{4\cdot 40}{1}=160 \ kg$

$\frac{3}{10}\cdot 1000=\frac{3\cdot 100}{1}=300 \ kg$

$\frac{9}{40}\cdot 1000=\frac{9\cdot25}{1}=225 \ kg$

$\frac{6}{8}\cdot 1000 = \frac{6\cdot125}{1}=750 \ kg$

$\frac{1}{10}\cdot 1000 = \frac{100}{1}=100 \ kg$

$\frac{17}{125} \cdot 1000 = \frac{17\cdot 8}{1}=136 \ kg$

б)

$\frac{7}{8}=\frac{7\cdot 125}{8\cdot 125}=\frac{875}{1000} \ t$

$\frac{4}{25}=\frac{4\cdot 40}{25\cdot 40}=\frac{160}{1000} \ t$

$\frac{3}{10}=\frac{3\cdot 100}{10\cdot 100}=\frac{300}{1000} \ t$

$\frac{9}{40}=\frac{9\cdot 25}{40\cdot 25}=\frac{225}{1000} \ t$

$\frac{6}{8}=\frac{6\cdot 125}{8\cdot 125}=\frac{750}{1000} \ t$

$\frac{1}{10}=\frac{1\cdot 100}{10\cdot 100}=\frac{100}{1000} \ t$

$\frac{17}{125}=\frac{17\cdot 8}{125\cdot 8}=\frac{136}{1000} \ t$

$100<136<160<225<300<750<875 \\ \\ \frac{100}{1000}<\frac{136}{1000}<\frac{160}{1000}<\frac{225}{1000}<\frac{300}{1000}<\frac{750}{1000}<\frac{875}{1000} \\ \\ \frac{1}{10}<\frac{17}{125}<\frac{4}{25}<\frac{9}{40}<\frac{3}{10}<\frac{6}{8}<\frac{7}{8}$
