Cara Dan Jawaban

1. \: \frac{12}{14} \times \frac{14}{16} = \frac{3}{1} \times \frac{14}{16} = \frac{3}{1} \times \frac{1}{4} = \frac{3}{1 \times 4} = \frac{3}{4}

2. \: \frac{3}{5} \times 2 \frac{3}{4} = \frac{3}{5} \times \frac{11}{4} = \frac{3 \times 11}{5 \times 4} = \frac{33}{5 \times 4} = \frac{33}{20}

3. \: 36 \frac{15}{20} \times \frac{24}{32} = \frac{147}{4} \times \frac{24}{32} = \frac{441}{16}

4. \: 6 \frac{5}{10} \times 4 \frac{10}{7} = \frac{13}{2} \times 4 \frac{10}{7} = \frac{13}{2} \times \frac{38}{7} = \frac{247}{7}

5. \: \frac{21}{25} \times \frac{18}{21} \times \frac{5}{4} = \frac{1}{5} \times \frac{18}{21} \times \frac{5}{4} = \frac{1}{5} \times \frac{9}{1} \times \frac{5}{4} = \frac{1}{5} \times \frac{9}{1} \times \frac{1}{2} = \frac{1 \times 9 \times 1}{5 \times 1 \times 2} = \frac{9}{5 \times 2} = \frac{9}{10}

6. \: 38 \frac{24}{30} \times 18 \frac{19}{24} = \frac{194}{5} \times 18 \frac{19}{24} = \frac{194}{5} \times \frac{451}{24} = \frac{43.747}{60}

7.16 \frac{15}{18} \times 11 \frac{9}{16} = \frac{101}{6} \times 11 \frac{9}{16} = \frac{101}{6} \times \frac{185}{16} = \frac{18.685}{96}

8. \: \frac{5}{17} \times \frac{8}{20} \times \frac{6}{31} = \frac{1}{17} \times \frac{2}{1} \times \frac{6}{31} = \frac{1 \times 2 \times 6}{17 \times 1 \times 31} = \frac{2 \times 6}{17 \times 31} = \frac{12}{527}

9. \frac{8}{20} \times \frac{5}{23} \times \frac{5}{14} = \frac{1}{1} \times \frac{1}{23} \times \frac{5}{7} = \frac{1 \times 1 \times 5}{1 \times23 \times 7} = \frac{1 \times 5}{23 \times 7} = \frac{5}{161}

10. \: 20 \frac{4}{24} \times \frac{7}{18} = \frac{121}{6} \times \frac{7}{18} = \frac{847}{108}
