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

1)3 5/6-1 2/15=3 25/30-1 4/30 = 2 21/30= 2 7/10
2) 2 7/10 * 5/9 = 27/10 * 5/9 = 3/2 = 1 1/2
3)1/20+0,24=1/20+6/25=5/100+24/100=29/100
4)29/100 * 8 1/3=29/100 * 25/3=29/12=2 5/12
5)2 5/12 - 1 1/6=2 5/12 - 1 2/12 = 1 3/12 = 1 1/4
6)1 1/4 * 2 =5/4 * 2 =5/2 = 2 1/2
