▪2 2/3 + 2 2/3(7 1/5:6 - 1/10×2) = 5 целых 1/3
1) 7 1/5 : 6 = 36/5 × 1/6 = 6/5 = 1 1/5
2) 1/10 × 2= 2/10 = 1/5
3) 1 1/5 - 1/5 = 1
4) 2 2/3 × 1 = 2 2/3
5) 2 2/3 + 2 2/3 = 4 4/3 = 5 1/3
▪(3 1/3-1 1/3×2 1/2):(2 1/4-1 1/6) = 0
1) 1 1/3 × 2 1/2 = 4/3 × 5/2 = 10/3 = 3 1/3
2) 3 1/3 - 3 1/3 = 0
3) 2 1/4 - 1 1/6 = 2 3/12 - 1 2/12 = 1 1/12
4) 0 ÷ 1 1/12 = 0
