1. Do you mean 19-7 in 26? 19/26-7/26 =19-7/26 =12/26 = 6/13 solution: the addition and subtraction with the same denominator only need to deal with the numerator, and the denominator remains unchanged. 2. Do you want to ask the score of 5-2 and 16? 416/16-29/16 = (4-2) (16-9/16) = 27/16 solution: integer part and decimal part. 3. Do you want to ask 9-? 8 22/22-17/22 = (8-1) (22-7/22) = 715/22 Solution: Calculate the integer part and the decimal part respectively. 4. Do you want to ask 2 14 9-65438+? 29/14-3/14 = 29-3/14 = 26/14 = 23/7 solution: the integer part and the decimal part are calculated separately. 5. Do you want to ask 3 28 3-28 17? 3 3/28-17/28 = 2 31/28-17/28 = 214/28 = 212 Solution: Calculate the integer part and the decimal part separately (/kloc) kloc-0/ 1/654388 13/2 1-4 20/2 1 = 7 34/2 1-4 20/2 1 =(7-4)(34-20/2 1)= 3 14/2 1 = 3 2/3 Solution: Calculate the integer part and the decimal part separately (1=265438 Do you want to ask 6-3 32 15-32 13? 6-315/32-13/32 = 5 32/32-315/32-13/32 = (5-3) (32-132) Kloc-0/ = 1 Are you asking 19-25, 6-2 and 1 1? 519/25-6/25-21/25 = (5-2) (19-6-1/25) = 3 2. 9 13/36-8 23/36- 15/36 = 8 49/36-8 23/36- 15/36 = (8-8) (49-23- 15/36)

Q 1。 I guess you want to ask [19] ... [7] ... [19-7] ... [12] ... [6] _ _ _ _ = _ _ _
Typing is hard to score, and it is hard to bring scores.
Or expressed in the following way:19/26-7/26 = (19-7)/26 =12/26 = 6/13 = = = Q2 .............. 9 ... 6 = 5-[2 _ 9/ 16]= 5-2-(9/ 16)= 3-(9/ 16)=(3x 16-9)/ 16 =(48-9)/ 16 = 39/ 16 = 2 _(7/ 16) ...
Count others yourself. 2008-03-1901:48: 55 Supplement: 5-[2 _ 9/16] = {(5x16)-(2x16)+9.
