Answer 1

(62 23-4 18)+(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
