81:9x6=54
42:6x2=14
54:9x5=30
8x2:4=4
64:8x4=32
24:8x9=27

32:4x6=48

Answer 2

60 : 10 x 8 = 6 x 8 = 48
45 : 5 x 8 = 9 x 8 = 72

7 x 4 : 7 = 28 : 7 = 4
64 : 8 x 2 = 8 x 2 = 16

81 : 9 x 6 = 9 x 6 = 54
42 : 6 x 2 = 7 x 2 = 14

54 : 9 x 5 = 6 x 5 = 30
8 x 2 : 4 = 16 : 4 = 4

63 : 7 x 4 = 9 x 4 = 36
24 : 8 x 9 = 3 x 9 = 27

9 x 4 : 6 = 36 : 6 = 6
32 : 4 x 6 = 8 x 6 = 48.
