\(\frac{131313}{171717}=\frac{131313:10101}{171717:10101}=\frac{13}{17}\)
a) \(\frac{171717}{292929}=\frac{171717:10101}{292929:10101}=\frac{17}{29}\)
b) \(\frac{3344}{1212}=\frac{3344:4}{1212:4}=\frac{836}{303}\)
c) \(\frac{20192019}{20172017}=\frac{20192019:10001}{20172017:10001}=\frac{2019}{2017}\)
a) 17/29(chia cho 10101)
B) 836/303( chia 4)
C) 2019/2017(chia 10001)
1313/1717 = ( 1313 :101)/(1717:101)=13/17
171717/191919=(171717:10101)/(191919:10101)=17/19
231231/343343=(231231:7007)/(343343:7007)=33/49
373737/494949=(373737:10101)/(494949:10101)=37/49
a) 1414 − 2121 = 1414 : − 707 − 2121 : − 707 = − 2 3 ;
b) − 131313 − 171717 = − 131313 : ( − 10101 ) − 171717 : − 10101 = 13 17 .
\(\dfrac{1313}{1717}=\dfrac{101x13}{101x17}=\dfrac{13}{17}\)
\(\dfrac{131313}{171717}=\dfrac{10101x13}{10101x17}=\dfrac{13}{17}\)
Vậy \(\dfrac{1313}{1717}=\dfrac{131317}{171717}\)
\(\dfrac{1313}{1717}và\dfrac{131313}{171717}\\ \dfrac{1313}{1717}=\dfrac{13}{17}\\ \dfrac{131313}{171717}=\dfrac{13}{17}\\ \Rightarrow\dfrac{1313}{1717}=\dfrac{131313}{171717}\)
A) 17/23
B) 193/197
