Tolong plisssssssssssss

Halo :) 
Saya akan membantu menjawab pertanyaanmu, no.1 dan 2 sudah sama rekan sebelumnya jadi saya akan jawab dari 3 - 10

[tex]3. \frac{12}{10} : \frac{48}{10} = \frac{12}{10} * \frac{10}{48} = \frac{12}{48} \\ 4. \frac{72}{10} : \frac{3}{10} = \frac{72}{10} * \frac{10}{3} = \frac{72}{3} \\5. \frac{6}{8} : \frac{2}{10} = \frac{6}{8} * \frac{10}{2} = \frac{60}{16} \\6. \frac{8}{25} : \frac{25}{10} = \frac{8}{25} * \frac{10}{25} = \frac{80}{625} \\7. \frac{21}{10} : \frac{5}{8} = \frac{21}{10} * \frac{8}{5} =\frac{168}{50} [/tex]

[tex]8. \frac{7}{2} : \frac{75}{100} = \frac{7}{2} * \frac{100}{75} = \frac{700}{150} \\9. \frac{5}{100} : \frac{5}{4} = \frac{5}{100} * \frac{4}{5} = \frac{20}{500} \\10. \frac{15}{100} : \frac{7}{5} = \frac{15}{100} * \frac{5}{7} = \frac{75}{700} [/tex]

kalau membantu silahkan pilih jawaban terbaik diantara kami berdua...
Thanks
