TOT IN FRACTIE ZECIMALA

72,(603)=
54,(81)=
12,(7)=

Answer 1

$\it 12,(7) =12\dfrac{7}{9} = \dfrac{115}{9}$

$\it 54,(81) = 54\dfrac{\ 81}{99}^{(9} =54\dfrac{9}{11}=\dfrac{603}{11}$

$\it 72,(603) = 72\dfrac{\ 603^{(9}}{999} =72\dfrac{67}{111}=\dfrac{8095}{111}$

$\it 192,8=\dfrac{1928^{2)}}{10} =\dfrac{964}{5}$

$\it52,012 =\dfrac{52012^{(4}}{1000}=\dfrac{13003}{250}$

$\it 31,48 = \dfrac{3148^{(4}}{100} = \dfrac{787}{25}$

$\it \dfrac{308}{75}=308:75= 4, 10(6)$
