199=0,(0,1);199=0,(0,1);
1999=0,(001)
1/99=0,(0,1);199=0,(0,1);
1/999=0,(001)1999=0,(001)
\(\dfrac{1}{99}=0,\left(01\right)\)
\(\dfrac{1}{999}=0,\left(001\right)\)
Ta có :
1/99 = 0,(01)
1/999 = 0,(001)
Ta có: \(\dfrac{1}{99}\)= 0, (01) có thể viết là 0,010101...
\(\dfrac{1}{99}\)= 0, (001) có thể viết là 0,001001001...
Lời giải :
\(\dfrac{1}{99}=0,\left(0,1\right)\)
\(\dfrac{1}{999}=0,\left(001\right)\)
\(\dfrac{1}{99}=0,\left(01\right);\dfrac{1}{999}=0,\left(001\right)\)
1/99= 0.01010101
1/999= ko ra dc to quá
\(\dfrac{1}{99}=0,01;\dfrac{1}{1999}=0,001\)
\(\dfrac{1}{99}=0.010101...=0,\left(01\right)\)
\(\dfrac{1}{999}=0.001001001...=0,\left(001\right)\)
