\(\frac{10.20+40}{20.6+120}=\frac{10.20+20.2}{20.6+20.6}\)
\(=\frac{20.\left(10+2\right)}{20\left(6+6\right)}=\frac{20.12}{20.12}\)
\(=\frac{1}{1}=1\)
\(\frac{10.20+40}{20.6+120}\)
\(=\frac{10.20+20.2}{20.6+20.6}\)
\(=\frac{20.\left(10+2\right)}{20.\left(6+6\right)}\)
\(\frac{20.12}{20.12}=1\)
\(\frac{10.20+40}{20.6+120}\)
\(=\frac{200+40}{120+120}\)
\(=\frac{240}{240}=1\)
