\(\frac{677.874+251}{678.874-623}\)
\(=\frac{677.874+251}{\left(677+1\right).874-623}\)
\(=\frac{677.874+251}{677.874-1.874-623}\)
\(=\frac{677.874+251}{677.874+874-623}\)
\(=\frac{677.874+251}{677.874+251}\)
\(=1\)

677 x 875 + 163/678 x 874 - 34
= 592375 + 71231/339 - 34
= 592585,1209 - 34
= 592551,1209

\(\frac{637\times527-189}{526\times637+448}\)
\(=\frac{637\times\left(526+1\right)-189}{526\times637+448}\)
\(=\frac{637\times526+637-189}{526\times637+448}\)
\(=\frac{637\times526+448}{526\times637+448}\)
