\(\left(13\frac{1}{4}-2\frac{5}{27}-10\frac{3}{6}\right)\)\(.230\frac{1}{25}+46\frac{3}{4}\)

\(=\)\(\left(\frac{53}{4}-\frac{59}{27}-\frac{21}{2}\right)\)\(.\frac{5751}{25}+\frac{187}{4}\)

\(=\frac{304803}{100}-\frac{12567}{25}-\frac{120771}{50}+\frac{187}{4}\)

\(=\frac{304803}{100}-\frac{50268}{100}-\frac{241542}{100}+\frac{4675}{100}\)

\(=\frac{304803-50268-241542+4675}{100}\)

\(=\frac{17668}{100}\)

\(=\frac{4417}{25}\)
