\(\frac{7}{8}+0,5+\frac{3}{4}+0,125-\frac{75}{100}\)
\(=\frac{7}{8}+\frac{1}{2}+\frac{3}{4}+\frac{1}{8}-\frac{3}{4}\)
\(\left(\frac{7}{8}+\frac{1}{8}\right)+\left(\frac{3}{4}-\frac{3}{4}\right)+\frac{1}{2}\)
\(\frac{8}{8}+0+\frac{1}{2}\)
\(1+0+\frac{1}{2}\)
\(1+\frac{1}{2}\)
\(\frac{2}{2}+\frac{1}{2}\)
\(=\frac{3}{2}\)
