1.FBP dari 18,48,36 [tex]2. \sqrt[3]{6859} [/tex] 3.berat sebuah mobil bermuatan pasir 35 karung adalah 6675 ton apa bila setiap karung berisi 25 kilogram pasir

1. FPB
18 = 2 x 3 x 3
[tex]18 = 2 \times {3}^{2} [/tex]
48 = 2 x 2 x 2 x 2 x 3
[tex]48 = {2}^{4} \times 3[/tex]
36 = 2 x 2 x 3 x 3
[tex]36 = {2}^{2} \times {3}^{2} [/tex]
FPB = 2 x 3 = 6

[tex]2. \sqrt[3]{6859} = 19[/tex]
3.
mobil + 35 karung = 6675 ton
1 karung = 25 kg

35 karung = 35 x 25 = 875 kg

1 ton = 1000 kg
875 kg = 875/1000 = 0,875 ton

berat mobil
= 6675 - 0,875
= 6674,125 ton

4. kec = jarak/waktu
kec = 45 km/jam
waktu =
10.65
07.45
--------- -
03.20
= 3 20/60
= 10/3

jarak = ? km

45 = x : 10/3
x = 45 x 10/3
x = 15 x 10
x = 150 km
