задание по математике 2 целых 2/3: 2 целых + (4/15+2/5):(3 целых 1/3*3/5)

2 2/3 : 2 + (4/15 + 2/5) : (3 1/3 * 3/5) = 1 2/31) 4/15 + 2/5 = 4/15 + 6/15 = 10/15 = 2/32) 3 1/3 * 3/5 = 10/3 * 3/5 = 10/5 = 23) 2 2/3 : 2 = 8/3 : 2 = 8/3 * 1/2 = 4/3 = 1 1/34) 2/3 : 2 = 2/3 * 1/2 = 1/35) 1 1/3 + 1/3 = 1 2/3

2 2/3:2+(4/15+2/5):(3 1/3*3/5)=1 1/3+(4/15+6/15):(10/3*3/5)=1 1/3+10/15:2=1 1/3+1/3=1 2/3
