Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

Yang A.

$(2 \times 4\frac{3}{8}) - 5 \frac{3}{4} \\ \\ = ( \frac{2}{1} \times \frac{35}{8} ) - \frac{23}{4} \\ \\ = (\frac{1}{1} \times \frac{35}{4} ) - \frac{23}{4} \\ \\ = \frac{35}{4} - \frac{23}{4} = \frac{12}{4} = 3$

Yang B.

$1.25 - (0.5 \times \frac{1}{4} ) \\ \\ = \frac{125}{100} - ( \frac{5}{10} \times \frac{1}{4} ) \\ \\ = \frac{5}{4} - ( \frac{1}{2} \times \frac{1}{4} ) \\ \\ = \frac{5}{4} - \frac{1}{8} = \frac{10 - 1}{8} = \frac{9}{8} = 1 \frac{1}{8}$

Yang C.

$\frac{1}{4} + (1.5 \div 0.25) \\ \\ = \frac{1}{4} + ( \frac{15}{10} \div \frac{25}{100} ) \\ \\ = \frac{1}{4} + ( \frac{3}{2} \div \frac{1}{4} ) \\ \\ = \frac{1}{4} + ( \frac{3}{2} \times \frac{4}{1} ) \\ \\ = \frac{1}{4} + ( \frac{3}{1} \times \frac{2}{1} ) = \frac{1}{4} + \frac{6}{1} = \frac{1 + 24}{4} = \frac{25}{4} = 6 \frac{1}{4}$

Yang D.

$(2 \frac{4}{5} \times \frac{1}{8} ) - 0.25 \\ \\ = ( \frac{14}{5} \times \frac{1}{8} ) - \frac{25}{100} \\ \\ = ( \frac{7}{5} \times \frac{1}{4} ) - \frac{1}{4} \\ \\ = \frac{7}{20} - \frac{1}{4} = \frac{7 - 5}{20} = \frac{2}{20} = \frac{1}{10}$

Yang E.

$14.1 \div (1 \frac{3}{5} + 15\%) \\ \\ = \frac{141}{10} \div ( \frac{8}{5} + \frac{15}{100} ) \\ \\ = \frac{141}{10} \div ( \frac{8}{5} + \frac{3}{20} ) \\ \\ = \frac{141}{10} \div ( \frac{32 + 3}{20} ) \\ \\ = \frac{141}{10} \div \frac{35}{20} = \frac{141}{10} \div \frac{7}{4} = \frac{141}{10} \times \frac{4}{7} \\ \\ = \frac{141}{5} \times \frac{2}{7} = \frac{282}{35} = 8 \frac{2}{35}$
