\(\frac{121.75.130.169}{39.60.11.198}\)

Answer 1

\(\frac{121.75.130.169}{39.60.11.98}\)=\(\frac{199377750}{2522520}\)=\(\frac{46475}{588}\)

Answer 2

\(\frac{121.75.130.196}{39.60.11.198}\)

\(=\frac{11.11.3.5.5.2.5.13.}{3.13.3.2.2.5.11.11.3.3.2}\)

\(=\frac{11^2.3.5^3.2.13}{3^4.13.2^3.5.11^2}\)

\(=\frac{5^2}{3^3.2^2}\)

\(=\frac{25}{27.4}\)

\(=\frac{25}{108}\)
