Пошаговое объяснение:

5 * 4/5 + 2 = 20/5 + 2 = 4 + 2 = 6

17 * 3/34 + 1/2 = 1 * 3/2 + 1/2 = 3/2 + 1/2 = 4/2 = 2

6/15 * (1. 1/3 + 5/6) =

2/5 * (1. 2/6 + 5/6) = 2/5 * 1. 7/6 = 2/5 * 13/6 = 1/5 * 13/3 = 13/15

(5 + 8. 1/2) * 8/27 =

13. 1/2 * 8/27 = 27/2 * 8/27 = 8/2 = 4

(14. 8/9 + 10. 1/3) * 9/43 =

(14. 8/9 + 10. 3/9) * 9/43 =

24. 11/9 * 9/43 = 25. 2/9 * 9/43 = 227/9 * 9/43 = 227/43 = 5. 12/43

1) 5*4/5+2=4+2=6

5/1*4/5=4/1=4

2)17*3/34=17/1*3/34=1/1*3/2=3/2=1 1/2=1,5

1 1/2+1/2=3/2+1/2=4/2=2

3)6/15*(1 1/3+5/6)=13/15

1 1/3+5/6=4/3+5/6=8/6+5/6=13/6=2 1/6

6/15*2 1/6=6/15*13/6=1/15*13/1=13/15

4)5+8 1/2=13 1/2=13,5

13 1/2*8/27=27/2*8/27=1/1*4/1=4/1=4

5)14 8/9+10 1/3=14 8/9+10 3/9=24 11/9=25 2/9

25 2/9*9/43=227/9*9/43=227/43=5 12/43
