Materi:
[tex] \frac{x}{y} = \frac{persentase \: x}{persentase \: y} [/tex]
Misalkan: Banyak wiraswasta= x, maka banyak pedagang= x-60.
Berarti:
[tex] \frac{pedagang}{wiraswasta} = \frac{15}{25} = \frac{3}{5} [/tex]
[tex] \frac{x - 60}{x} = \frac{3}{5} [/tex]
5x-300=3x
2x=300 maka x=150 dapat wiraswasta= 150
Karna 150 org = 25 % => 6 org = 1%
Berarti Petani= 6 × 35= 210 0rg
