(3 целых 5/6-1 целую 2/15)*5/9+((1/20+0,24(десятичная дробь)*8 целых 1/3-1 целую 1/6)*2? умоляю!

(3 5/6 - 1 2/15)*5/9 + ((1/20+0,24)*8 1/3 - 1 1/6)*2 =

3 5/6 - 1 2/15 = 3 25/30 - 1 4/30 = 2 21/30 = 2 7/10
2 7/10*5/9 = 27/10*5/9=3/2 = 1 1/2

1/20+0,24 = 0,05+0,24=0,29
0,29*8 1/3 = 29/100* 25/3 = 29/12 = 2 5/12
2 5/12 - 1 1/6= 2 5/12 - 1 2/12 = 1 3/12 = 1 1/4
1 1/4*2 = 5/2 = 2 1/2

1 1/2 + 2 1/2 = 4
