2 2/3 /2+(4/15+2/15) /(3 1/3*3/5) = 1 8/15
1) 4/15 + 2/15 = 6/15
2) 3 1/3 * 3/5 = 10/3 * 3/5 = 2
3) 2 2/3 : 2 = 8/3 : 2 = 8/3 * 2/1 = 4/3
4) 6/15 : 2 = 6/15 * 1/2 = 3/15 = 1/5
5) 4/3 + 1/5 = 23/15 = 1 8/15
2.1/4+((1.1/2+2.2/3):3.3/4-2/3):8.8/9=8 1/20
1) 1 1/2+2 2/3=25/6
2) 25/6: 3 3/4= 10/9
3) 10/9-2/3=4/9
4) 2 :1/4=8
5) 4/9: 8 8/9=1/20
6) 8+1/20=8 1/20
