1195/6-61/12-27/9= 19 30/36 - 6 3/36 -2 28/3/ = (19 - 6 - 2) + (30/36 - 3/36 - 28/36) = 11 - 1/36 = 10 36/36 - 1/36 = 10 35/36

2) 117/10 - 57/30 - 3 4/15 = 1121/30 - 57/30 - 38/30 = 11-5-3)+ (21/30 - 7/30 - 8/30) = 3 + 6/30 = 36/30 = 31/5

3) 9 14/15 - 21/5 - 47/10 = 928/30 - 2 6/30 - 4 21/30 = (9 - 2 - 4) + (28/30 - 6/30 - 21/30) = 3 + 1/30 = 3 1/3 * C

1 / (20 3/8) - (6 - 2 1/6) = 20 3/8 - 3 5/6 = 20 9/24 - 3 20/24 = 19 33/24 - 320/24 = 16 13/24

5) 281/20 - (7 - 28/15) = 281/20 - 47/15 = 28 3/60 - 2 18/60 = 2763/60 - 428/60 = 2335/60 = 237/12

) 29 3/25 - (4 - 21/5) = 29 3/25 - 14/5 = 29 3/25 - 1 20/25 = 28 28/25 - 120/25 = 278/25
