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

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

c) 637 x 527 - 189=335510 / 526 x 637 + 448=335510
d) 677 x 874 + 251 =591949 / 678 x 874 - 623=591949

677 x 875 + 163/678 x 874 - 34
= 592375 + 71231/339 - 34
= 592585,1209 - 34
= 592551,1209
nhớ T I C K cho mình nha
677x875-163/678x874-34
=592375+71231/339-34
=592585,1209-34
