7 14/15+2 1/15= 119/15 = 31/15 = 150/15 = 10
9 24/27+12 13/27= 267/27 + 337/27 = 604/27 = 22 10/27
1-12/19= 19/19 - 12/19 = 7/19
8-3 6/15= 120/15 - 51/15 = 69/15 = 23/5 = 4 3/5
12-11 6/11= 132/11 - 127/11 = 5/11
16 3/13-6 8/13= 211/13 - 86/13 = 125/13 = 9 8/13
13 4/9-2 8/9= 121/9 - 26/9 = 95/9 =10 5/9
10 7/16-4 12/16= 167/16 - 76/16 = 91/16 =5 11/16
29 49/53-8 49/53= 1586/53 - 473/53 = 1113/53 = 21
(20 16/25 +13 9/25)-(23 4/14 +7 13/14)= (516/25 + 334/25) - (326/14 + 111/14) =
850/25 - 437/14 = 11900 /350 - 10925/350 = 975/350 = 2 275/350 = 2 11/14
