ada yg bisa gak? pakai cara ya.. nomer 9 dan 10

[tex] 12\frac{1}{4} : 5 = \frac{49}{4} : 5 = \frac{49}{4} x \frac{1}{5} = \frac{49}{20} = 2\frac{9}{20}m [/tex][tex] 
1\frac{1}{2}x5= \frac{3}{2} x 5 = \frac{15}{2} [/tex] kg

9. 12[tex] \frac{1}{4} : 5 = \frac{49}{4} : \frac{5}{1} = \frac{49}{4} x \frac{1}{5}= \frac{49}{20} = 2,45 m[/tex]

10.[tex]1 \frac{1}{2} x 5 = \frac{3}{5} x \frac{5}{1} = \frac{15}{5} = 3kg[/tex]

jadikan yg terbaik ya :D
