diketahui nilai a:b:c =3:5:4 dan 2a+5b+4c=160 . tentukan nilai a,b dan c!

2a + 5b + 4c = 160
6x : 25x : 16x = 160
3x + 5x + 4x = 40
12x = 40
x = 40/12
x = 1/3

a = 2 × 3 1/3
a = 3 × 10/3
a = 30/3 = 10

b = 5 × 10/3
b = 50/3
b = 26 2/3

c = 4 × 10/3
c = 40/3
c = 13 1/3

Jadikan jawaban terbaik ya jika berkenan.. terimakasih ^^
