Jawaban:
3.) B.14
4.) C.
[tex] \frac{7}{4} = 1.6 = 1 \frac{2}{6} = 30\%[/tex]
Penjelasan dengan langkah-langkah:
[tex]3.) \: \: \: \: \: \: \: ( - 3 + 10) \times 8 \div ( - 2 + 6) = \\ (10 - 3) \times 8 \div ( - 2 + 6) = \\ 7 \times 8 \div (6 - 2) = \\ 7 \times 8 \div 4 = \\ 56 \div 4 = \\ 14[/tex]
[tex]4.) \: \: \: 30\% = \frac{3}{10} \\ \\ \frac{7}{4} \\ \\ 1\frac{2}{6} = \frac{1 \times 6 + 2}{6} \\ = \frac{8 \div 2}{6 \div 2} \\ 1 \frac{2}{6} = \frac{4}{3} \\ \\ 1.6 = \frac{16}{10} \\ \frac{16 \div 2}{10 \div 2} = \frac{8}{5} \\ 1.6 = \frac{8}{5} \\ \\ \frac{7}{4} > \frac{8}{5} > \frac{4}{ 3} > \frac{3}{10} \\ \\ \frac{7}{4} > 1.6 > 1 \frac{2}{6} > 30\%[/tex]
