\(a,5,\left(6\right)=\dfrac{17}{3}\\ b,0,\left(15\right)=\dfrac{5}{33}\\ c,1,\left(36\right)=\dfrac{15}{11}\\ d,7,1\left(18\right)=\dfrac{783}{110}\\ e,0,01\left(6\right)=\dfrac{1}{60}\\ f,0,21\left(3\right)=\dfrac{16}{75}\)
a) 5,(6) = 5 + 2/3 = 17/3
b) 0,(15) = 15/99 = 5/33
c) 1,(36) = 1 + 36/99 = 15/11
d) 7,1(18) = 783/110
e) 0,01(6) = 1/60
f) 0,21(3) = 16/75
