ПОМОГИТЕ!!!!!! ПРОШУ!!!!!! (31\43 - 23\43) + (1 + 15\43) (14\133 + 92\133) - (1 - 104\133)

[latex]( \frac{31}{43} - \frac{23}{43} )+(1+ \frac{15}{43} )= \frac{8}{43} +1 \frac{15}[latex]( \frac{14}{133} + \frac{92}{133} )-(1- \frac{104}{133} )= \frac{116}{133} - \frac{29}{133} = \frac{87}{133} [/latex]{43} =1 \frac{13}{43} [/latex]

(31/43 - 23/43) + (1+15/43)=8/43+1 15/43= 1 23/43 (14/133 + 92/133) - (1 - 104/133)=106/133 -29/133=77/133
