minta tolong kak, dengan cara

1 ²/⁷ x 1 ²/⁵ = ​

[tex]1 \frac{2}{7} \times 1 \frac{2}{5} [/tex]

Pertama diubah ke pecahan biasa, karena perkalian

[tex] = \frac{9}{7} \times \frac{7}{5} [/tex]

bisa dibagi 7

[tex] = \frac{9}{7 \div 7} \times \frac{7 \div 7}{5} [/tex]

[tex] = \frac{9}{1} \times \frac{1}{5} [/tex]

[tex] = \frac{9 \times 1}{1 \times 5} [/tex]

[tex] = \frac{9}{5} [/tex]

[tex] = 1 \frac{4}{5} [/tex]

__PENYELESAIAN__

[tex]1 \frac{2}{7} \times 1 \frac{2}{5} \\ = \frac{9}{7} \times \frac{7}{5} \\ = \frac{63}{35} \div 7 \\ = \frac{9}{5} \: \: \: \: \: \: \: \: \: [/tex]
