jila banyak ikan mas dan ikan lele 240,ekor dan lele28% mas20% mujaer12% nila16% Gurame24% berapa jumlah ikan seluruhnya

mas + lele = 240
lele = 28%
mas = 20%
mujair = 12%
nila = 16%
gurame = 24%
lele : mas ; mujair : nila : gurame = 28 : 20 : 12 : 16 : 24 = 7 : 5 : 3 : 4 : 6
lele = 7/12 × 240 = 140 ekor
mas = 5/12 × 240 = 100 ekor
mujair = 3/5 × 100 = 60 ekor
nila = 4/5 × 100 = 80 ekor
gurame = 6/5 × 100 = 120 ekor
jumlah ikan seluruhnya = 140 + 100 + 60 + 80 + 120 = 500 ekor
