Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

Nomor 2a

\frac{1}{2} + \frac{2}{3} \\ \\ = \frac{3 + 4}{6} \\ \\ = \frac{7}{6} \\ \\ = 1 \frac{1}{6}

\\

Nomor 2b

\frac{4}{5} + \frac{2}{6} \\ \\ = \frac{24 + 10}{30} \\ \\ = \frac{34}{30} \\ \\ = 1 \frac{4}{30}

\\

Nomor 2c

3 \frac{1}{3} + 5 \frac{1}{2} \\ \\ = \frac{10}{3} + \frac{11}{2} \\ \\ = \frac{20 + 33}{6} \\ \\ = \frac{53}{6} \\ \\ = 8 \frac{5}{6}

\\

Nomor 2d

2 \frac{1}{2} + 5 \frac{6}{10} \\ \\ = \frac{5}{2} + \frac{56}{10} \\ \\ = \frac{50 + 112}{20} \\ \\ = \frac{162}{20} \\ \\ = 8 \frac{2}{20} \\ \\ = 8 \frac{1}{10}

\\

Nomor 3a

\frac{5}{8} + 0.7 + 2 \frac{1}{2} \\ \\ = \frac{5}{8} + \frac{7}{10} + \frac{5}{2} \\ \\ = \frac{25 + 28 + 100}{40} \\ \\ = \frac{153}{40}

\\

Nomor 3b

34\% + 4.28 + \frac{1}{15} \\ \\ = \frac{34 \: \footnotesize{\div 2}}{100\: \footnotesize{\div 2}} + \frac{428\: \footnotesize{\div 4}}{100\: \footnotesize{\div 4}} + \frac{1}{15} \\ \\ = \frac{17}{50} + \frac{107}{25} + \frac{1}{15} \\ \\ = \frac{51}{150} + \frac{642}{150} + \frac{10}{150} \\ \\ = \frac{703}{150}

\\

Nomor 3c

3 \frac{8}{25} + 125\% + 4.6 \\ \\ = \frac{83}{25} + \frac{125}{100} + \frac{46}{10} \\ \\ = \frac{332 + 125 + 460}{100} \\ \\ = \frac{917}{100}

\\

Nomor 3d

\frac{4}{8} + 35\% + \frac{7}{20} \\ \\ = \frac{4\: \footnotesize{\div 4}}{8\: \footnotesize{\div 4}} + \frac{35\: \footnotesize{\div 5}}{100\: \footnotesize{\div 5}} + \frac{7}{20} \\ \\ = \frac{1}{2} + \frac{7}{20} + \frac{7}{20} \\ \\ = \frac{10 + 7 + 7}{20} \\ \\ = \frac{24}{20}

\\

Nomor 4

\frac{1}{7} + \frac{1}{2} \\ \\ = \frac{2 + 7}{14} \\ \\ = \frac{9}{14} \: liter

\\

Nomor 5

2 \frac{1}{4} + 5 \frac{3}{5} \\ \\ = \frac{9}{4} + \frac{28}{5} \\ \\ = \frac{45 + 112}{20} \\ \\ = \frac{157}{20} \\ \\ =7\frac{17}{20} \: kg
