TOLONG JAWAB DGN PECAHAN BIASA plis jawab nanti aku jadiin yg terbaik 1.2,5×75%= 2.5 1/3×0,4= 3.45%÷0,5= 4.3,25×3/5= 5.5/6×0,3= 6.90%×0,9= 7.3/8×0,83= PERTANYAA

1.
[tex] \frac{250}{100} \times \frac{75}{100} = \frac{18750}{10000} = 1.875[/tex]
2.
[tex] \frac{16}{3} \times \frac{4}{10} = \frac{64}{30} [/tex]
3
[tex] \frac{45}{100} \times \frac{10}{5} = \frac{450}{500} = \frac{900}{1000} = 0.9[/tex]
itu 0,5 diubah jadi 5/10 kemudian dibalik jadi 10/5 karena merubah pembagian jadi perkalian

4
[tex] \frac{325}{100} \times \frac{6}{10} = \frac{1950}{1000} = 1.95[/tex]
5
[tex] \frac{5}{6} \times \frac{3}{10} = \frac{15}{60} [/tex]
6
[tex] \frac{90}{100} \times \frac{9}{10} = \frac{810}{1000} = 0.81[/tex]
7
[tex] \frac{3}{8} \times \frac{83}{100} = \frac{249}{800} = ( \frac{249 \times 125}{800 \times 125} ) = \frac{31125}{100000} = 0.31125[/tex]
1
[tex] \frac{21}{10} \times \frac{4}{10} = \frac{84}{100} = 0.84[/tex]
2
[tex] \frac{3}{4} \times \frac{15}{100} = \frac{45}{400} = ( \frac{45 \times 25}{400 \times 25} ) = \frac{1125}{10000} = 0.1125[/tex]
3
[tex] \frac{5}{6} \times \frac{54}{100} = \frac{270}{600} = \frac{9}{20} [/tex]
270 dan 600 sama sama dibagi 30

4
[tex] \frac{88}{100} \times \frac{3}{8} = \frac{264}{800} = 0.33[/tex]
