Ta có :
\(\frac{204204}{217217}=\frac{204204:1001}{217217:1001}=\frac{204}{217}\)
\(\frac{414141}{494949}=\frac{414141:10101}{494949:10101}=\frac{41}{49}\)
\(\frac{171171171}{180180180}=\frac{171171171:9009009}{180180180:9009009}=\frac{19}{20}\)
204204/217217 = 204/217
414141/494949 = 41/49
171171171/180180180=171/180
đúng 100% luôn
