tolong dijawab pakai cara

1. 8/8 - 3/8 = 5/8
2. hasan : anin
8 : 6 =14
perbandingan
hasan : jumlah kelereng mereka
8. : 14
4. :7
3. jp = 2 3/5 = 2,6 cm
s = 1: 1.500.000
js = jp : s
= 2.6 : 1.500.000
= 1.733
4. 23/6 = 0.38
5. 56/20 =2,8
6. 65/25 =2,6
7. 287 % = 0,287
8. 1,5 x 1 1/2 = 1,5 = 1 1/2
= 3/2 x3/2 =9/4
9. 3,6 : 1,5 =36/10 : 15/10 = 36/10 x 10/15
= 18/5 =3 3/5
10. jp = pxl = 8,5 x3 = 25,5 cm
s = 1:6000
js = jp/s = 25,5 / 6000 =0,00425
12. js = 85 km = 8.500.000 cm
jp = 3 2/5 cm =3,4 cm
s = jp : js
= 3,4 : 8.500.000
= 1 : 2.500.000
13. 84/108 = 42/54=7/9
14. 67/8 = 8 3/8
15 1.75 x 2,4 : 48% =
175/100 x 24/10 x 100/48 = 35/4 =8 3/4
maaf klo slh
