Answer 1

\(\frac{3131}{3535}=\frac{3131:101}{3535:101}=\frac{31}{35}\)

\(\frac{204204}{217217}=\frac{204204:1001}{217217:1001}=\frac{204}{217}\)

\(\frac{414141}{180180}=\frac{414141:273}{180180:273}=\frac{1517}{660}\)

\(\frac{171171171}{180180180}=\frac{171171171:9009009}{180180180:9009009}=\frac{19}{20}\)
