3.16 1) 50 21/33 - ( 4 1/6 + 25 9/11) = 50 42/66 - ( 4 11/66 + 25 54/66) = 50 42/66 - 29 65/66 = 49 108/66 - 29 65/66 = 20 43/66

НОК (11;33;6)= 66

2) 27 2/9 + (16 43/45 - 5 11/15) = 27 18/45 + (16 43/45 - 5 33/45) = 27 18/45 + 11 10/45 = 38 28/45

НОК (9;15;45) = 45

3) 43 17/25 - (9 18/25 - 4 111/125) = 43 85/125 - ( 9 90/125 - 4 111/125) = 43 85/125 - ( 8 215/125 - 4 111/125) = 43 85/125 - 4 104/125 = 42 210/125 - 4 104/125 = 38 106/125

НОК (25;125) = 125

4) (29 11/18 + 14 7/12) - 5 13/24 = (29 44/72 + 14 42/72) - 5 39/72 = 44 14/72 - 5 39/72 = 43 86/72 - 5 39/72 = 38 47/72

НОК (18;24;12) = 72

3.17 1) (13-8 9/10) + (26 1/2 - 15 1/5) - (14 1/5 - 7) + (3 3/10 + 8 1/2) = (13 - 8 9/10) + (26 5/10 - 15 2/10) - (14 2/10 -7) + (3 3/10 + 8 5/10) = 4 1/10 + 11 3/10 - 7 2/10 + 11 8/10 = 15 4/10 - 7 2/10 + 11 8/10 = 8 2/10 + 11 8/10 = 20

НОК (2;5;10) =10

2) ( 62 2/3 - 4 1/8) + (14 - 11 5/9) - (39 - 1 19/24) - ( 1 4/9 + 2 1/3) = ( 62 48/72 - 4 9/72) + (14 - 11 40/72) - (39 - 1 57/72) - ( 1 32/72 + 2 24/72) = 58 39/72 + 3 40/72 - 38 57/72 - 3 64/72 = 62 9/72 - 38 57/72 - 3 64/72 = 61 81/72 - 38 57/72 - 3 64/72 = 23 24/72 - 3 64/72 = 22 96/72 - 3 64/72 = 19 24/72 = 19 1/3

НОК (8;3;9;24) = 72
