Answer
$28.4405$
Work Step by Step
$\frac{5.68+(0.9)^{2}\div100}{0.2}$
$=(5.68+(0.9)^{2}\div100)\div0.2$
$=(5.68+(\frac{9}{10})^{2}\div100)\div0.2$
$=(5\frac{68}{100}+(\frac{9}{10}\times\frac{9}{10})\div\frac{100}{1})\div\frac{2}{10}$
$=(\frac{568}{100}+\frac{81}{100}\div\frac{100}{1})\div\frac{1}{5}$
$=(\frac{568}{100}+\frac{81}{100}\times\frac{1}{100})\times\frac{5}{1}$
$=(\frac{568}{100}+\frac{81}{10,000})\times\frac{5}{1}$
$=(\frac{56,800}{10,000}+\frac{81}{10,000})\times\frac{5}{1}$
$=\frac{56,881}{10,000}\times\frac{5}{1}$
$=\frac{284,405}{10,000}$
$=28\frac{4,405}{10,000}$
$=28.4405$
