Explicație pas cu pas:
1600 x 1/8 = 200
rest 1600 - 200 = 1400
1400 x 2/5 = 560
Rest 1400 - 560 = 840
2 intregi si 1/2 = 5/2
6,5 = 65/10 = 13/2
a/(5/2) = b/5 = c/(13/2) = k
2a/5 = b/5 = 2c/13 = k
a = 5k/2
b = 5k
c = 13k/2
a + b + c = 840
5k/2 + 5k + 13k/2 = 840
5k/2 + 10k/2 + 13k/2 = 840
28k/2 = 840
k = 840*2/28 = 60
a = 5*60/2 = 150
b = 5*60 = 300
c = 13*60/2 = 390
Numerele sunt
200; 560; 150; 300; 390
