\(\frac{5.18-10.27+15.36}{10.36-20.54+30.72}\)
\(=\frac{5.18-5.2.27+5.3.36}{10.36-10.2.54+10.3.72}\)
\(=\frac{5.18-5.54+5.108}{10.36-10.108+10.216}\)
\(=\frac{5.\left(18-54+108\right)}{10.\left(36-108+216\right)}\)
\(=\frac{5.72}{10.144}\)
\(=\frac{1.1}{2.2}\)
\(=\frac{1}{4}\)

\(\frac{5.18-10.27+15.36}{10.36-20.54+30.72}\)
\(=\frac{5.18-\left(5.2\right).27+\left(5.3\right).36}{\left(5.2\right).36-\left(5.4\right).54+\left(5.6\right).72}\)
\(=\frac{5.18-5.\left(2.27\right)+5.\left(3.36\right)}{5.\left(2.36\right)-5.\left(4.54\right)+5.\left(6.72\right)}\)
\(=\frac{5.18-5.54+5.108}{5.72-5.216+5.432}\)
\(=\frac{5.\left(18-54+108\right)}{5.\left(72-216+432\right)}\)
\(=\frac{5.\left(-36+108\right)}{5.\left(-144+432\right)}\)
\(=\frac{5.72}{5.288}\)
\(=\frac{5.72}{5..4.72}\)
\(=\frac{1}{4}\)
\(\frac{5.18-10.27+15.36}{10.36-20.54+30.72}\)
\(=\frac{5.18-10.27+15.36}{5.2.18.2-10.2.27.2+15.2.36.2}\)
\(=\frac{5.18-10.27+15.36}{5.8.2.2-10.27.2.2+15.36.2.2}\)
\(=\frac{1}{2.2-2.2+2.2}\)
\(=\frac{1}{2.2}=\frac{1}{4}\)
15,56 + 14,41 = 29,97
4,25 - 0.12 = 4,13
15.36 x 12.25 = 188,16
15.56 + 14.41 = 29.97
4.25 - 0.12= 4.13
