jawab no.8,9,10 ya pakai jalan!!

8.[tex] \frac{9}{4} : \frac{6}{10} =\frac{9}{4} x \frac{10}{6} =\frac{3}{4}[/tex]
9.3,75 hektar-0,4 hektar-1,26 hektar=2,09 hektar
10.70% dari Rp 80.000 =Rp 56.000

8. 2 1/4 : 6/10= 9/4 x 10/6 = 3 3/4 = d .
9.3 3/4 - 2/5 - 1,26 = 3,75-0,40 - 1,26 = 2,09 = a.
10. 100%-30% = 70% = 70/100 x 80.000,00 = 56.000,00 = d.
