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

\(\frac{677\times874+251}{678\times874-623}\)
\(=\frac{677\times874+251}{\left(677+1\right)\times874-623}\)
\(=\frac{677\times874+251}{677\times874+874-623}\)
\(=\frac{677\times874+251}{677\times874+251}\)

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

+/ \(\frac{16.25+44.100}{29.96+142.48}=\frac{16.25+4.11.100}{29.96+71.2.48}\) +/\(\frac{1996.1995-996}{1000+1996.1994}=\frac{\left(1995+1\right).1995-996}{1000+1996\left(1995-1\right)}\)
\(=\frac{400+400.11}{29.96+71.96}=\frac{400\left(1+11\right)}{96\left(29.71\right)}\) \(=\frac{1995.1995+1995-996}{1000+1996.1995-1996}\)
