Question

calculeaza fracțiile zecimale :
2,31(6)
0,15(32)
560,0(81)
​

Answer 1

2,31(6) = (2316-231)/900 = 2085/900 simplificat cu  15 = 139/60

0,15(32) = (1532-15)/9900 = 1517/9900

560,0(81) = (560081-5600)/990 = 554481/990 simplificat cu 9 = 61609/110

Answer 2

$\it 2,31(6)=2\dfrac{316-31}{900}=2\dfrac{\ \ 285^{(15}}{900}=2\dfrac{19}{60}\\ \\ \\ 0,15(32)=\dfrac{1532-15}{9900}=\dfrac{1517}{9900}\\ \\ \\ 560,0(81)=560\dfrac{\ \ 81^{(9}}{990}=560\dfrac{9}{110}$
