посчитайте заранее спасибо 2) (62 2/3 - 4 1/8) + (14-11 5/9) - (39-1 19/24) - (1 4/9 +2 1/3​

(62 2\3-4 1\8)+(14-11 5/9)-(39-1 19/24)-(1 4/9+

2 1/3)

1) 62 2/3-4 1/8=58+(2/3-1/8)=58+(16/24-3/24)=

58 13/24

2( 14-11 5/9)=2 4/9

3)39-1 19/24=37 5/24

4)1 4/9+2 1/3=3+(4/9+3/9)= 3 7/9

5)58 13/24+2 4/9=60+(13/24+4/9)=

60+(39/72+32/72)=60 71/72

6)60 71/72-37 5/24=23 + (71/72-15/72)=

23 56/72=23 7/9

7)23 7/9-3 7/9=20
