(6 3/5 ÷ 6 - 8,016 × 0,125 + 5/12 × 0,03) × 2 3/4 = 2431/8000
1) 6 3/5 ÷ 6 = 33/5÷6 = 6,6÷6=1,1
2)8,016 × 0,125 = 1,002
3)5/12 × 0,03 = 5/12 × 3/100 = 1/80
4)1,1-1,002=0,098
5)0,098 + 1/80 = 98/1000 + 1/80 = 49/500 + 1/80 = (49 × 4 + 1 × 25)/2000 = 196/2000 + 25/2000 = 221/2000
6)221/2000 × 2 3/4 = 221/2000 ×11/4 = 2431/8000
