Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

Jawaban:

1) \frac{1}{3} \times \frac{4}{5} = \frac{4}{15}

2) \frac{1}{4} \times \frac{6}{5} = \frac{6}{20} = \frac{3}{10}

3) \frac{1}{8} \div 3 \\ = \frac{1}{8} \div \frac{3}{1} \\ = \frac{1}{8} \times \frac{1}{3} \\ = \frac{1}{24}

4)8 \times \frac{1}{30} \\ = \frac{8}{1} \times \frac{1}{30} \\ = \frac{8}{30} \\ = \frac{4}{15}

5) \frac{2}{5} + \frac{1}{3} \\ = \frac{6}{15} + \frac{5}{15} \\ = \frac{11}{15}

6)3 \frac{1}{4} - \frac{6}{7} \\ = \frac{13}{4} - \frac{6}{7} \\ = \frac{91}{28} - \frac{24}{28} \\ = \frac{67}{28} \\ = 2 \frac{11}{28}

7)2 \frac{7}{8} + 4 \frac{5}{7} \\ = (2 + 4) + \frac{7}{8} + \frac{4}{7} \\ = 6 + \frac{49}{56} + \frac{32}{56} \\ = 6 + \frac{81}{56} \\ = 6 \frac{81}{56}

8)9 \times \frac{1}{4} \div 1 \frac{1}{5} \\ = \frac{9}{1} \times \frac{1}{4} \div \frac{6}{5} \\ = \frac{9}{1} \times \frac{1}{4} \times \frac{5}{6} \\ = \frac{45}{24} \\ = \frac{15}{8} \\ = 1 \frac{7}{8}

9)5 \div \frac{2}{3} \\ = \frac{5}{1} \times \frac{3}{2} \\ = \frac{15}{2} \\ = 7 \frac{1}{2}

10) \frac{3}{4} - \frac{5}{8} \\ = \frac{6}{8} - \frac{5}{8} \\ = \frac{1}{8}

11) \frac{2}{7} + 3 \frac{1}{2} \\ = \frac{2}{7} + \frac{7}{2} \\ = \frac{4}{14} + \frac{49}{14} \\ = \frac{53}{14} \\ = 3 \frac{11}{14}

12)3 + \frac{4}{5} - 2 \frac{1}{6} \\ = \frac{3}{1} + \frac{4}{5} - \frac{13}{6} \\ = \frac{90}{30} + \frac{24}{30} - \frac{65}{30} \\ = \frac{114}{30} - \frac{65}{30} \\ = \frac{49}{30} \\ = 1 \frac{19}{30}

13) \frac{2}{7} + 3 + \frac{1}{4} \\ = \frac{2}{7} + \frac{3}{1} + \frac{1}{4} \\ = \frac{8}{28} + \frac{84}{28} + \frac{7}{28} \\ = \frac{99}{28} \\ = 3 \frac{15}{28}

14)5 \frac{2}{3} \times ( \frac{3}{8} \div \frac{1}{4}) \\ = \frac{17}{3} \times ( \frac{3}{8} \div \frac{2}{8} ) \\ = \frac{17}{3} \times ( \frac{3}{8} \times \frac{8}{2}) \\ = \frac{17}{3} \times \frac{24}{16} \\ = \frac{408}{48} \\ = \frac{51}{6} \\ =8 \frac{3}{6}

15)4 \frac{1}{3} \div 5 \\ = \frac{13}{3} \div \frac{5}{1} \\ = \frac{13}{3} \times \frac{1}{5} \\ = \frac{13}{15}

16)2 - 1 \frac{1}{3} \\ = \frac{2}{1} - \frac{4}{3} \\ = \frac{6}{3} - \frac{4}{3} \\ = \frac{2}{3}

17)9 \frac{1}{2} - ( \frac{1}{4} + 7 \frac{2}{3}) \\ = \frac{19}{2} - ( \frac{1}{4} + \frac{23}{3}) \\ = \frac{114}{12} - ( \frac{3}{12} + \frac{92}{12}) \\ = \frac{114}{12} - \frac{95}{12} \\ = \frac{19}{12} \\ = 1 \frac{7}{12}

18)7 \frac{1}{2} - 2 \frac{3}{4} \\ = \frac{15}{2} - \frac{11}{3} \\ = \frac{45}{6} - \frac{22}{6} \\ = \frac{23}{6} \\ = 3 \frac{5}{6}

19)3 \frac{2}{3} + 7 \frac{1}{4} \\ = (3 + 7) + ( \frac{2}{3} + \frac{1}{4}) \\ = 10 + \frac{8}{12} + \frac{3}{12} \\ = 10 + \frac{11}{12} \\ = 10 \frac{11}{12}
