Tolong dijawab pakai cara ya.

1. S?
25 km=........cm
=25 × 100.000
=2.500.000 cm

[tex]s = \frac{jp}{js} = \frac{10}{2.500.000 } = \frac{1}{250.000} [/tex]
2. JP?
45 km=.........cm
= 45 × 100.000
= 4.500.000

[tex]jp = s \times js \\ = \frac{1}{150.000} \times 4.500.000 \\ = \frac{1}{15} \times 450 = 30 \: cm[/tex]
3. S?
25 m=......... cm
= 25 × 100
=2.500 cm
[tex]s = \frac{jp}{js} = \frac{50}{2.500} = \frac{1}{50} [/tex]
4. S?
60 m=..... cm
=60 × 100
=6.000 cm
[tex]s = \frac{jp}{js} = \frac{50}{6.000} = \frac{1}{120} [/tex]
5. JP?
20 m=........cm
= 20 × 100
= 2.000 cm
[tex]jp = s \times js \\ = \frac{1}{250} \times 2.000 \\ = \frac{1}{25} \times 200 = 8 \: cm[/tex]
Semoga membantu!!
