20% = 60
5% = x
20x = 300
x = 15

Nelayan 25% maka 25/5= 5
15 x 5 = 75 orang

Petani 40% maka 40/5=8
15 x 8 = 120 orang

TNI 15% maka 15/5 = 3
15 x 3 = 45 orang

Total jumlah penduduknya
Buruh 60 + nelayan 75 orang + petani 120 orang + TNI 45 orang =
300 orang

Jawaban:

 nelayan \ : frac{60}{x} = frac{20}{25} \ 20x = 1500 \ x = frac{1500}{20} \ x = 75

tni \ frac{60}{x} = frac{20}{15} \ 20x = 900 \ x = frac{900}{20} \ x = 45

petani \ frac{60}{x} = frac{20}{45} \ 20x = 1800 \ x = frac{1800}{20} \ x = 90
