Explicație pas cu pas:
0,08(3) = (83-8)/900 = 75/900
0,0(6) = 6/90
Map = (x×3 + (75/900)×(5) + (6/90)×(6)) / ( 3+5+6)
0,1 = (3x + 375/900 + 36/90) / 14
0,1 = [(2700x + 375 + 360)/900] / 14
1/10 = [(2700x + 375 + 360)/900] / 14
14 = [(2700x + 375 + 360)/900] x 10
14 = (2700x + 375 + 360)/90
14×90 = 2700x + 375 + 360
1260 = 2700x + 735
1260 - 735 = 2700x
525 = 2700x
x = 525/2700
x = 0,19(4)
