\(\frac{19}{4}+\frac{37}{100}+\frac{1}{8}+\frac{1}{2}+\frac{163}{100}+\frac{3}{8}\)
\(=\frac{19}{4}+\frac{37}{100}+\frac{163}{100}+\frac{1}{8}+\frac{3}{8}+\frac{1}{2}\)
\(=\frac{19}{4}+2+\frac{1}{2}+\frac{1}{2}\)
\(=\frac{19}{4}+2+1\)
\(=\frac{19}{4}+3\)
\(=\frac{31}{4}\)

\(\frac{19}{4}+\frac{37}{100}+\frac{1}{8}+\frac{1}{2}+\frac{163}{100}+\frac{3}{8}\)
\(=\left(\frac{19}{4}+\frac{1}{2}\right)+\left(\frac{37}{100}+\frac{163}{100}\right)+\left(\frac{1}{8}+\frac{3}{8}\right)\)
\(=\frac{21}{4}+2+\frac{1}{2}\)
\(=5,25+2+0,5\)
\(=7,75\)
