Tolong bantu lg ya kk no 9 & 10.. maksih

9.
[tex] 2\frac{5}{14} + 0.7 \div \frac{1}{5} - 25\% \\ \frac{33}{14} + (\frac{7}{10} \div \frac{1}{5}) - \frac{25}{100} \\ \frac{33}{14} + \frac{35}{10} - \frac{25}{100} \\ \frac{3300}{1400} + \frac{4900}{1400} - \frac{350}{1400} \\ \frac{8.550}{1400} = \frac{342}{56} = \frac{171}{28} = 6 \frac{21}{28} \\ 6 \frac{3}{4} = 6.75[/tex]
10.
[tex]g \: \div j = 2 \div 3 \\ jumlah = 620 \\ 2 + 3 = 5 \\ g = \frac{2}{5} \times 620 = 248 \\ j = \frac{3}{5} \times 620 = 372 \\ jumlah = 248 + 372 = 620 \\ selisih = 372 - 248 = 124[/tex]
