1. `A=2 1/315. 1/651-1/105 .3 650/651-frac\{4}{315.651}+4/105`

   `A=631/315. 1/651-1/105. 2603/651- frac\{4}{315.651}+4/105`

   `A=frac\{631}{315.651}-frac\{2063}{105.651}-frac\{4}{315.651}+4/105`

   `A=(frac\{631}{315.651}-frac\{4}{315.651})+(frac\{-2603}{105.651}+4/105)`

   `A=frac\{627}{315.651}+(frac\{-2603}{105.651}+frac\{651.4}{105.651})`

   `A=frac\{627}{315.651}+frac\{1}{105.651}`

   `A=frac\{627.105}{315.651.105}+frac\{315}{315.651.105}`

   `A=2/651`

2. `A = 2 1/315 . 1/651 – 1/105 . 3 650/651 – 4/{315.651} + 4/105`  

   `-> A = 631/315 . 1/651 – 1/105 .  2603/651 – 4/{315. 651} + 4/105`

   `-> A = {631}/{315 . 651} – {2063}/{105 . 651} – 4/{315.651} + 4/105`

   `-> A = (631/{315.651} – 4/{315.651} ) + (  {-2603}/{105 . 651} + 4/105 )`

   `-> A =  627/{315 . 651} + (  {-2603}/{105.651} + {651 . 4}/ { 105 . 651} )`

   `-> A = {627}/{315.651}+  ( {-2603}/{105.651} + {2604}/{105.651} )`

   `-> A = 627/{315.651} + 1/{105.651}` 

   `-> A = {627 . 105}/{315.105 . 651} + {315}/{105.651.315}`

   `-> A =   {65835+315}/{315.105.651}`

   `-> A = 2/651`

   Vậy `A = 2/651`
