1.)3/5:7/10(jwbanya pke cara) 2.)2 16/19:9/19 Pliss jwbannya pke cara yaaa.!!!

[tex]1) \frac{3}{5} \div \frac{7}{10} \\ = \frac{3}{5} \times \frac{10}{7} \\ = \frac{6}{7} \\ 2) 2 \frac{16}{19} \div \frac{9}{19} \\ = \frac{54}{19} \times \frac{19}{9} \\ = 6[/tex]

1.
[tex] = \frac{3}{5} \div \frac{7}{10} \\ = \frac{3}{5} \times \frac{10}{7} \\ = \frac{30}{35} \\ = \frac{6}{7} [/tex]
2.
[tex] = \frac{16}{9} \div \frac{9}{19} \\ = \frac{16}{9} \times \frac{19}{9} \\ = \frac{304}{81} [/tex]
