bisa bantu saya besok di kumpul badian c dan d semua nya kalau bisa

C....
1. 3/7 =3 : 7 (c)
2. 21 : 42= 1 : 2 (f)
3. p =7x400=2800cm=20m
l = 4x 400=1600cm=16m
L= pxl = 20x16 =320maaf ga ada di opsi
4. B=9/4 x36 =81. (a)
5. 3,25 x 1.000.000=3.250.000cm=32,5km (k)
6. alas=8x 200=1.600cm=16m
tinggi=5x200=1.000cm=10m
L= 1/2x16x10= 80m² (e)
7. D= 9/8 x 32=36
36 +32 =68. (h)
8. 6x 2.500 =15.000. (g)
9. E = 4/6 x48 = 32. (i)
10. T =6/5 x20 =24. (b)

D....
1) Rina : Bela = 5 : 4
5 + 4 = 9
Rina = 5/9 x 63 = 35
Bela = 4/9 x 63 = 28
2) Rudi : Reza = 3 : 8
3 + 8 = 11
Rudi = 3/11 x 93.500 = 25.500
reza = 8/11 x 93.500 = 68.000
