tolong yang bisa :)
pakek cara kak​

[tex]2 \frac{2}{8} \div 2 \frac{4}{8} \div 1 \frac{9}{12} [/tex]

Bisa diaederhanakan dlu,

[tex]2 \frac{1}{4} \div 2 \frac{1}{2} \div 1 \frac{3}{4} \\ \\ = \frac{9}{4} \div \frac{5}{2} \div \frac{7}{4} \\ \\ = \frac{9}{4} \times \frac{2}{5} \times \frac{4}{7} \\ \\ = \frac{9}{1} \times \frac{2}{5} \times \frac{1}{7} \\ \\ = \frac{18}{35} [/tex]

Penjelasan dengan langkah-langkah:

[tex]2 \frac{2}{8} \div 2 \frac{4}{8} \div 1 \frac{9}{12} [/tex]

semua dijadikan pecahan

[tex] \frac{18}{8} \div \frac{20}{8} \div \frac{21}{9} [/tex]

jadikan kali

[tex] \frac{18}{8} \times \frac{8}{20} = \frac{18}{20} = \frac{9}{10} [/tex]

[tex] \frac{9}{10} \times \frac{9}{21} = \frac{27}{70} [/tex]
