A = 0,(36) - 0,(71)
= 36/99 - 71/99
= -35/99
B = [3,(12) - 2,(5)] : 0,(14)
= (103/33 - 203/99) : 14/99
= 106/99 : 14/99
= 53/7
\(A=0,\left(36\right)-0,\left(71\right)\)
\(A=\dfrac{36}{99}-\dfrac{71}{99}=-\dfrac{35}{99}=-0,\left(35\right)\)
\(B=\left[3,\left(12\right)-2,\left(5\right)\right]:0,\left(14\right)\)
\(B=\left(\dfrac{3\cdot99+12}{99}-\dfrac{2\cdot9+5}{9}\right):\dfrac{14}{99}\)
\(B=\left(\dfrac{309}{99}-\dfrac{23}{9}\right):\dfrac{14}{99}\)
\(B=\dfrac{56}{99}:\dfrac{14}{99}\)
\(B=4\)
A=0,(36)-0,(71)
A=\(\dfrac{4}{11}\)-\(\dfrac{71}{99}\)
A=\(\dfrac{-35}{99}\)
B=[3,(12)-2,(5)]:0,(14)
B=[\(\dfrac{103}{33}\)-\(\dfrac{23}{9}\)]:\(\dfrac{14}{99}\)
B=\(\dfrac{-50}{33}\):\(\dfrac{14}{99}\)
B=\(\dfrac{-75}{7}\)
